[fxruby-users] Troubles with FXTextField encoding

Hello Jeroen, people. I''m having troubles with the encoding. First of
all, I''ll tell you that in the app that am developing am using ???????
characters. I''ve realized that when the user write some of those
characters and the app take it for work with it, later I come with troubles,
that''s because the string taked from the #FXTextField has ascii-8bit
encoding, and as you can see here:
http://www.sciencebuddies.org/science-fair-projects/project_ideas/CompSci_ASCII_Table.shtml
the characters ??????? doesn''t exist. So I''ve tried to change
the encoding of the #FXTextField to UTF-8 but I didn''t found the right
Constant: http://rubydoc.info/gems/fxruby/frames , am I missing it? is somewhere
hidding? nevermind. This is a little worse: I''ve tried to change the
encoding as I said to another one, not UTF-8(because I didn''t find it)
but to CP850, so I did something like this:
#...tf = FXTextField.new(parent, 10)tf.font=(app, FXFont.new(app, "Segoe
UI,90,normal,5,0,#{FONTENCODING_CP850},0"))#checking the encoding..puts
tf.encoding#=> 850
 Seems to work, but it doesn''t. When I enter text in the #FXTextField,
press enter and ask for the encoding, ascii-8bit appears, not cp850...
tf.connect(SEL_COMMAND) do |sender, selector, data|  puts data.encoding  #=>
<Encoding:ASCII-8BIT>end
 So I really don''t know what happen when the user enter any of
???????,... I''m getting strange errors when I handle those writed
strings. Do any of you have some advice about this? will be thankfull to hear
them. Is this a bug? Thanks for your time.
P.D.: By the way I''m using FXRuby 1.6.25, Windows 7 Proffesional 64
bits, Ruby 1.9.3p327 (2012-11-10) [i386-mingw32].

[fxruby-users] Troubles with FXTextField encoding

Perhaps if anybody can respond me again this old question I can solution this
problem:
ashraf01 wrote Oct 09, 2007; 11:54am
 How could I take unicode characters(Chinese, Japanese etc) as Input using
FXTextField.I am using WindowsXp & also setting Language options from the
control panel.I am very new in this environment. Could anybody help
plz..........
the only response was:
At the moment i doubt this is not possible. FOX does not support the input
methods API at the moment.
 It is solved now?
 Here is a little refresh of the problem: If I generate strings inside the
source code it gets the utf-8 encoding as expected, but at the moment of
re-assing a string to a variable doing it by the user in a #FXTextField, the
string becomes one with ascii-8bit encoding. So this is a big trouble for me
because Windows use CP1252 encoding in their box titles and Ruby raises an error
when I try to convert ascii-8bit into CP1252, even if I try to convert it into
utf-8 encoding. If I try to show up the string as it is now(with ascii-8bit
encoding) in a title in a #FXDialogBox I get strange characters. The fact is I
don''t know how the encoding works in the internals of Fox, how the
encoding works in an #FXTextField. There are rare things, for example: entering
"?" in a FXTextField, that value will be showed in a cell in a
#FXTable, it shows it correctly "?", when I show up that string in a
title of a FXDialoBox I get strange characters, not "?"; entering
"?" in a #FXTextField, that value will be showed as an item in a
#FXListBox and a #FXLabel, in both it shows "?", is not the same,
it''s downcased. So that''s why I can''t comprhend the
problem, is a strange behaviour.
 The solution?
 Meaby establish UTF-8 as encoding of any text typed in a #FXTextField, but I
don''t know how. I didn''t found documentation about it. Meaby I
can find another solution if knows how the internals works about the encoding.
 Thanks for your time, I''ll will appreciate your help.From:

 Thank you Jeroen for answer. Sadly seems that there''s no maintainer of
the framework for Ruby, and I don''t know how to check if the gem we(the
users of Ruby) download is compiled with -DUNICODE=1, Ruby is my first language
and I''m kind of noob related to C++.  I''m in middle of a
project, hope to get some answer about if FXRuby is compiled with that option,
if not if it can be fixed, etc. Does anybody knows that?

[fxruby-users] [Foxgui-users] Troubles with FXTextField encoding

Hi Dami?n,

sorry for responding so late. It is a spare time project for me and I
don''t know the fox toolkit that good, so I''ll have to try
things out or
look at the sources. Moreover I''m quite lazy in answering user
questions, generally.

Regarding your string encoding issue: FXRuby uses UTF-8 encoding for all
text strings since version 1.6.0. However the strings were not properly
marked as UTF-8 in Ruby-1.9. That is obviously a bug. You could set the
encoding of a string by hand per
String#force_encoding(''UTF-8'').

Please try out the new fxruby version 1.6.26.pre1 I just released. It
should now properly return UTF-8 strings for all text returning methods.

Some advices for unicode handling in fxruby: You should not use any
encodings but UTF-8 when interacting with fxruby. FXRuby will not check
or convert other encodings but will consider everything as UTF-8. You
moreover should mark all your *.rb files with a header line like this:

# encoding: utf-8

Then even Chinese characters should be no problem. There are also some
test cases in the test suite of fxruby for unicode handling.

Regarding the font encoding: I guess FONTENCODING_UNICODE should be the
suitable encoding for FXFont, but I didn''t tried it out.

Hope that helps.

Regards,
Lars

[fxruby-users] [Foxgui-users] Troubles with FXTextField encoding

Hi Lars, thanks for answer, I understand the facts.
 I''ve tried before the solution you propose without success, Ruby
raises an error when you try to convert(encode(Encoding::UTF_8)), or
point(force_encoding(Encoding::UTF_8)) ascii-8bit to UTF-8 for some reason.
 Now I''ve tried the pre-release of the 1.6.26 and works as a love, this
problem was scaring me but not anymore.
 For what I know the FONTENCODING_DEFAULT setted by default for all the Fonts
points to FONTENCODING_UNICODE, in words are the same, no necessity to change it
for me in anywhere.
 I use every Ruby file with #encoding: utf-8 up above. Thank you so much for
resolve this and to JVZ for respond the call.
 Regards. Dami?n-IgorJorobus.
