Rails - Mar 2010 - incompatible character encodings: ASCII-8BIT and UTF-8

Hello,

I just tried to migrate one of my applications from ruby 1.8 to ruby 1.9
and get following error:
  Showing app/views/layouts/application.html.erb where line #48  raised:
  incompatible character encodings: ASCII-8BIT and UTF-8

  48:     <%= render :partial => ''layouts/menu'' %>

I added "<%# coding: utf-8 %>" in application.html.erb and
layouts/_menu.rhtml but it still throws that error, anyone knows why?

I''ve been struggling with the same issue a few times, and the solution
that worked for me was to use a different mysql driver: ruby-mysql

# in config/environment.rb:
config.gem ''ruby-mysql''

# or in Gemfile:
gem ''ruby-mysql''

The encoding must also be set in config/database.yml:
 adapter: mysql
 encoding: utf8

No, all I found on google said I have to put it as a comment, <%- gives 
a syntax error.

I just run into the same problem in two other projects. Is there a way 
to set the encoding application wide?

You seem to have snipped the useful stuff.  How about encoding rather
than coding?  Though I am not convinced.

In every of my 4 projects with this error it always throws it when a 
special char is being displayed like ä, ö , ü, é, à etc.

It would be cool if I just need to paste some "# encoding: utf-8" or 
something somewhere and it recognizes everything as utf-8, is there 
anything like that I could do?

Hey,

First of all thanks but I tried what you said and well...
gem install ruby-mysql
config/environment.rb: added config.gem ''ruby-mysql''
config/database.yml: added adapter: mysql, encoding: utf8

But when I start the server I get following error:
=> Booting WEBrick
=> Rails 2.3.5 application starting on http://0.0.0.0:3000
D:/ruby19/lib/ruby/gems/1.9.1/gems/rails-2.3.5/lib/rails/gem_dependency.rb:119:Warning:

  ruby 1.9.1.378 at D:/ruby19/bin/ruby.exe

Run `rake gems:install` to install the missing gems.

I of course tried rake gems:install but it didn''t help. I also tried to
just uninstall the mysql gem but that didn''t work either. Any idea?

I''m ran into the same problems after switching to Ruby 1.9.1. Have you 
found a solution yet?

Not yet, had to switch back to Ruby 1.8.6.

Maybe someone else has an idea?

If you have have hard coded strings in ruby code you should try
Mystring ="bla bla"
Mystring.force_encoding(''ASCII-8BIT'')
Before using it.
For database strings you should search for mysql to force encoding
(this is for db created with ruby 1.8)
Good luck

That means if I do a "db:migrate:reset" (recreate the db with Ruby
1.9)
that error would disappear?

Most likely, you are outputting content stored in your DB as UTF-8 onto 
a template that is ASCII. This fix works for me: 
http://gist.github.com/273741 -- drop this into 
config/initializers/ruby_191_hacks.rb. I posted more about upgrading to 
1.9.1 here:

Are you sure you don''t have hard coded strings in the partial or
strings assigned
to variables through controller?

I''m only using I18n.t for strings and globalize2 for model translation.

Oh what I forgot. The icompati... error is showing on a line where I''m 
using I18n.t and it would return a string with a umlaut.

I am getting an error

incompatible character encodings: ASCII-8BIT and UTF-8


when I try to render a partial view for the children objects of a main
object''s edit page.

This is the controller method :

  def update
  @display_treatment = [
         {"exam type"=>"treatmenttype"} ,
         {"preparation comments"=>"preparation"},
         {"preparation nature"=>"natureprep"} ,
         {"reference cut"=>"refCoupe"},
         {"author"=>"author"},
         ]

    @echantillon = Echantillon.find(params[:id])
    @treatments = Treatment.find(:all, :conditions =>
[''echantillon_id
= ?'', @echantillon.id])

    respond_to do |format|
      if @echantillon.update_attributes(params[:echantillon])
        flash[:notice] = ''Echantillon was successfully
updated.''
        format.html { redirect_to(@echantillon) }
        format.xml  { head :ok }
      else
        format.html { render :action => "edit" }
        format.xml  { render :xml => @echantillon.errors, :status
=> :unprocessable_entity }
      end
    end
  end

and this is in the edit view:

      <%=  render  :partial => ''treatmentupdate'',
:locals =>
{:treatments => @echantillon.treatments} %>


and this is the partial:

<% @i = 1 %>

Hi,

did You find a solution? I have the same problem on all of my projects. 
DB in UTF8, rails in UTF8, but when it comes to partials with data with 
german umlauts I get the mentioned error.

As far as I understand it''s a problem with the erb rendering engine
that
forces ASCII encoding.

This encoding-thing is so digusting...

Greetings
Sven

forgot to say: a workaround that works for me is to add the method

from my database
eg.:

student.name.force_encoding(''utf-8'')

Good Night for now :-)

I tried with rails 3 (rc) and this adapter ruby-mysql and now everything 
works as expected!

Thanks a lot and now finally . Good Night!

As you figured out, the problem is to do with the old ''mysql''
gem not
being encoding-aware for Ruby 1.9. (You''re on Ruby 1.9, right?)

As an alternative to ruby-mysql, which is a little slow, you might
want to try the ''mysql2'' gem, which is an updated version of
the
original ''mysql'' gem, and which has native extensions to hook
into the
MySQL C library, making it faster.

Oh my god.........

first of all, the mysql2 gem works fine - thanks for the hint!

But there''s one more thing: I have lots of notices in my rails app like
"... wurde gelöscht". But when I have one of those fckng german
umlauts
in my controller I get this wonderful character encodings error message.

I''ll try to solve this with a locale and let You know...

Hi, I began reading this post because i have the same problem:

Just start the aplicacion with new ruby 1.9.2 raises the error

"incompatible character encodings: ASCII-8BIT and UTF-8".....

But I have the problem before reading database, in the main menu when 
ruby read "opción" and "menú"

Does anybody this solution, it seems easy.

thanks

First: Display text does not belong in the controller.  Keep it in the 
views (and perhaps the helpers).

Second: what is the encoding of the source file containing those 
characters?

Hi Albert,

I don''t understand this. Where are the words "opción" and
"menú"? In the
view there should be no problem.

Hi, thanks for responding.
It''s very simple, before acces any database, I have a presentation
menu,
and a text in the view saying than user have to choose an option:

<div id="tit_menu">
  <p>Seleccione una opción del menú</p>
</div>

If I change "ó" with "o" and "ú" with
"u" works fine.

It''s not a satisfying solution but whenever I ran into this problem I 
added
# Encoding: utf-8
to the top of the file causing this problem and it worked.

Would love to know how to get rid of all these comments and fix it for 
real though :)

Hi,

Just for your information - switching to ''mysql2'' gem solved
my issue -
I was storing Chinese in my DB..

Plus, mysql2 should be the default mysql adapter of Rails 3 anyways...

Hallo, I face a similar problem, but here mentioned solutions seem to
not work.

When I try to display string with non-ascii chars from a mysql database
in form, sometimes the program stops with the ''incompatible character
encodings: ASCII-8BIT'' error. This issue appears only at some fileds in
a table! Configuration of all fields is the same (varchar-string or
memo-text, encoding UTF-8).

For example:
I have record with 4 string fields, all have the same content (the same
word). When I try to display them, the ''incompatible...'' error
appears.
When I check their ''.encoding'', I get UTF-8 for three and
ASCII-8BIT for
one! Sometimes, when I render this template again and again, two are
ASCII and Two UTF. Strange - not?
I dont know about any difference among these fields configuration.

Yes, .enforce-coding(''utf-8'') added to all instance in erb
file works,
but it is not natty solution.

The same problem appears both at old project transformed from Ruby
1.8/rails 2.2 and at new project creatd in 5minutes via scaffolding in
ruby1,9,2/rails3.0.3.

The patch ''ruby_191_hacks.rb'' does not work here, I got the
same output
as ''Posted by Heinz Strunk (cojones) on 2010-04-06 11:49''

I have realized, that the template (erb file) must be saved in the same
coding, as the field are (i think the comment about UTF widely mentioned
above says to interpeter, that the file is in UTF coding)

My configuration:
Ruby 1.9.2, Rails 3.0.3 (3.0.1 behaves the same), mysql2 0.2.6 driver
(mysql 2.8.1 makes the same problem, mysql-ruby does not work here - it
misses an UNIX constant), both mysql2 and utf8 set in database.yml,
machine WinXP SP3.

Any idea, how to induce ActiveRecord to provide all the fields in the
UTF-8 encoding?

all,
Thanks for good ideas, but like for Robert K. it''s not working for me 
(ruby 1.9.2 and rails 3.0.3).

Robert K., check that your tables are of type = MyISAM and CHARACTER SET 
utf8 in Mysql.

I get the same error as you; the problem appears almost every time, but 
suddenly it works for again returning an error.

While we are waiting for a solution; how do you use encoding in the 
erb-files? -> "Yes, .enforce-coding(''utf-8'') added to
all instance in
erb file works" If you have the detail text in your file and the in 
witch erb-file do I have to put this encoding I would be very thankful.

Thanks again to all.

Er, why MyISAM?  That''s generally a poor idea, since you don''t
get
transactions or referential integrity.

(Of course, using MySQL itself is IMHO a poor idea...)

Because unfortunately innoDB tables don’t support full text searching of 
UTF-8 encoded content. But innoDB tables are more flexible in general.
Source of information: 
http://dev.mysql.com/doc/refman/5.1/en/fulltext-restrictions.html and 
http://www.dotmana.com/?p=95.
This might not be relevant, but could be.

Robert K. (or others), If you do have have the exact line for the 
enforce coding and in witch erb files to put it I would be happy.

PS:
I''ve tried <meta http-equiv="Content-Type"
content="text/html;
charset=utf-8" /> 
(http://www.igvita.com/2007/04/11/secure-utf-8-input-in-rails/) in the 
top of my app/views/layout/application.html.erb
I thought this would force the browser to use UFT-8. But not. I''m able 
to force the browser to show content after the page is read with right 
click- Encoding on screen (but only i just one of the string columns 
contains a special characters - strange).

I know that, but I didn''t think full-text searching was at issue here. 
Perhaps I misread.

The fact that you have to choose is a major reason that I no longer use 
or recommend MySQL.

Hey, I would recommend using Ruby 1.9.2 instead of Ruby 1.9.1.  Next,
mysql2 gems is not only faster than the ruby-mysql gem but it provides
the following benefits:

The Mysql2 gem is meant to serve the extremely common use-case of
connecting, querying and iterating on results. Some database libraries out
there serve as direct 1:1 mappings of the already complex C API’s available.
This one is not.

It also forces the use of UTF-8 [or binary] for the connection [and all
strings in 1.9, unless Encoding.default_internal is set then it’ll convert
from UTF-8 to that encoding] and uses encoding-aware MySQL API calls where
it can.
For more information, please see the following:

https://github.com/brianmario/mysql2

Good luck,

-Conrad

It''s a standard *nix patch file.  The patch command could read it (see 
its man page for more details), but the a/ and b/ file naming scheme 
means that you''d probably be better off using git apply.

Is possible use a patch command also under Windows? What about Git? Is 
it safe to install such patch for all the system also for ROR-beginners? 
Can I modify the source files manually (to exactly know, what have I 
changed)?

To replicate this error, call:

rails -v
> Rails 3.0.3
ruby - v
> ruby 1.9.2p0 (2010-08-18) [i386-mingw32]
Mysql version: 5.1.45-community-log

rails new r4_test -d mysql && cd r4_test
rails g scaffold post title:string content:string rem:text
rake db:create
rake db:migrate
rails s
http://localhost:3000/posts
call ''New Post''
to all three filends insert e.g. "löwe" or "tomáš"

After this I''ll get:
> incompatible character encodings: UTF-8 and ASCII-8BIT
Extracted source (around line #15):
12:
13: <p>
14:   <b>Rem:</b>
15:   <%= @post.rem %>
16: </p>
17:
18:


A monkey work-around
--------------------
line 18 in "app\views\posts\index.html.erb" change:
    <td><%= post.rem.force_encoding(''utf-8'')
%></td>

A better work-around
--------------------
1)add among the initializers:

class ActiveRecord::Base
  def force_utf
    attributes.each {|key, value|
value.force_encoding(''utf-8'') if
value.encoding != ''utf-8'' if value.kind_of?(String) }
  end
end

2)before first loading or using of a activerecord object in the template
(here it is a Post) I call .force_utf
e.g.
insert line 14 in "app\views\posts\index.html.erb"
 <%   post.force_utf %>

Changing InnoDb format of a table to Myisam does not help.
It is true, this problem does not appear with sqlite; but I have some
reasons to use MySQL.
I wonder, MySQL should be the couse of the problem - I have used the
same database type and revision and structure under 2.2.2 rails / 1.8
ruby without problems

I hope, next revision of ROR (3.0.4?) or mysql2 driver will solve this
problem.

Thanks! Perfect.

I''m also waiting for a fix in 3.0.4. As you asked: Does anyone know if 
patch and Git exists in windows? If no; how to apply std nix patch 
files?

About mysql og not. It''s religion, you know :-) I''ve used
Oracle on
Unix/Linux through many years. I like mysql, though.

Git exists in Windows.  A *nix-style patch command probably does too, 
but why are you torturing yourself with Windows? :)

SQLite (which Robert mentioned as his alternative) isn''t suitable for 
production.

I no longer trust MySQL, though, and I don''t see why others still do --
it''s got too many silly weaknesses and stupidities.  Given the choice, 
I''ll choose PostgreSQL every time.  Not religion, just being tripped up
one too many times by MySQL''s issues.

Best,

Hallo all,

Yes, but I don''t know to work with it and therefore I cannot imagine, 
how to update the core of rails without not to break it ):
> but why are you torturing yourself with Windows? :)
Well, most of my job I make on MS Excel tables with VBA support. Now I 
am trying to move to Rails, but it does not work yet... Maybe in some 
months I will be not more dependent on Bill''s products (:

It is not first time I hear someone prefers the postgresql...
A good comparison is on http://www.wikivs.com/wiki/MySQL_vs_PostgreSQL.

I decided to install a postgresql gem in my Rails to check it, but I 
failed with:
"Installing pg (0.10.0) with native extensions 
D:/Programs/ruby192/lib/ruby/1.9.1/rubygems/installer.rb:483:in `rescue 
in block in build_extensions'': ERROR: Failed to build gem native 
extension. (Gem::Installer::ExtensionBuildError)
D:/Programs/ruby192/bin/ruby.exe extconf.rb
checking for pg_config... no
checking for libpq-fe.h... *** extconf.rb failed ***
Could not create Makefile due to some reason, probably lack of
necessary libraries and/or headers.  Check the mkmf.log file for more"

(The same error after I ran either "gem install pg" or "bundle
install")

This is to much complicated for me to solve.

I note that you conveniently neglected to quote my point that a 
*nix-style patch tool also probably exists for Windows.  That or Git 
will apply a patchfile very nicely indeed.

Start now!  Use a *nix VM for Rails development.  I understand Virtual 
Rails is nice.

Well, stop complicating things further by using Windows!
