yes,I'm using wxruby2
When I change
"samples/text/unicode.rb" 's content:
require 'wx'
into
begin
require 'wx'
rescue LoadError => no_wx_err
begin
require 'rubygems'
require 'wx'
rescue LoadError
raise no_wx_err
end
end
and run unicode.rb in this way:
ruby -Ku unicode.rb
I got the error message like this:
unicode.rb:119: syntax error, unexpected tCONSTANT, expecting ')'
fd = Wx::FileDialog.new( nil, 'Import file', "",
"",
^
unicode.rb:128: warning: parenthesize argument(s) for future version
unicode.rb:128: syntax error, unexpected tCONSTANT, expecting kEND
Wx::MessageDialog.new(self, message, 'Wrong encoding',
^
and more ...
all the string cause error.
how can I do? Thanks

You could check whether the edited version is still valid UTF8 by doing: ruby -riconv -e ''Iconv.iconv("UTF-8", "UTF-8", File.read(ARGV[0]))'' samples/text/unicode.rb If this raises an IllegalSequenceError, then the script isn''t valid utf8. hth alex

However, the wxruby unicode sample does work fine here. I feel pretty sure that your problem is coming from using notepad to edit the file.> samples/text/aunicode.rb:1: Invalid char `\357'' in expression > samples/text/aunicode.rb:1: Invalid char `\273'' in expression > samples/text/aunicode.rb:1: Invalid char `\277'' in expressionI think notepad is inserting these invalid characters into the sample - I''d strongly suggest you try using Scite, a free programming editor which should have been installed alongside your ruby installation. You will find it a much more helpful editor for writing ruby scripts generally. I was able to fix these ''Invalid char'' errors by simply copying your code and pasting it into a new file in Scite, setting the encoding to UTF-8 (in File -> Encoding) and saving.> samples/text/unicode.rb:119: syntax error, unexpected tCONSTANT, > expecting '')'' > fd = Wx::FileDialog.new( nil, ''Import file'', "", "",Similarly, your example has a broken UTF8 character on line 91. You should be able to put a Chinese (or any other) string in the button label on that line in Scite, and it should work fine. hth Alex
it seems that ruby1.8 doesn''t support utf8 files with bomb .... but windows notepad only can save utf8 encoded files with bomb. when i save the file with :set fileencoding=utf-8 :set nobomb in vim. Things goes well. Scite is also a nice programming editor, :) Thanks a lot! 2007/4/12, Alex Fenton <alex at pressure.to>:> yang cao wrote: > >> Does the sample work if you don''t edit it?

Thank you! ye, BOM(Byte Order Mark), not bomb, hehe. cheers cy Alex Fenton ??:> yang cao wrote: > >> it seems that ruby1.8 doesn''t support utf8 files with bomb .... >> but windows notepad only can save utf8 encoded files with bomb. >> >> > Ah, thanks for the info, that makes sense.
