Rails - Jul 2006 - (bug) auto_complete_for has no support for umlauts!

i wanted to file a bug in the rubyonrails trac, since trac is currently 
broken, i am writing this here. maybe there is a solution allready:

auto_complete_for has no support for umlauts. this i a very big problem 
for non-english developers out there, since almost everything searched 
for contains umlauts.
* searching by umlauts is not possible
* displaying of the found entries is screwed

http://lists.rubyonrails.org/pipermail/rails/2006-April/033612.html

fix:
escape the search and the results.

affected file:
http://dev.rubyonrails.org/svn/rails/trunk/actionpack/lib/action_controller/macros/auto_complete.rb

after trying everything from the wiki.rubyonrails.org pages
http://wiki.rubyonrails.com/rails/pages/Internationalization
http://wiki.rubyonrails.com/rails/pages/HowToUseUnicodeStrings

the solution was quite trivial.

1. check that the database encoding is UTF8 (in PostgreSQL: Unicode) - 
sqlite on win32 should not be a problem

2. add a meta value to serve unicode documents to your layout
<meta http-equiv="Content-type" content="text/html;
charset=utf-8" />


tried everywhere with mongrel, works perfectly with umlauts (don''t 
forget that you english speaking ppl might use the term "doppelg?nger"
which is an english term with umlauts!)

this should also work for apache.

hope some other guys also post solutions, since i found loooooots of 
unanswered questions on this list/forum.

bye,
z3cko
