Were you able to inspect the decoded character values? If the decoding is right then the issue is with fonts. See isFontAvailable and installFont methods in LanguageEnvironment to see how to load language-specific fonts on startup. GreekEnvironment and JapaneseEnvironment classes depend on such external font files.
Also another question is in Squeak4.1 what could i do to make sure the the language environment I use is chinese or some others?
What is your locale setting? Inspect: Locale current localeID
SimplifiedChineseEnvironment>>supportedLanguages contains 'zh'
My understanding now in Squeak4.1 that the default language is UTF8 or Unicode, where could i do the switch?
Unfortunately not, because of the need for backward compability across multiple OSes and platforms. To select the right converter, use class side methods in SimplifiedChineseEnvironment. See JapaneseEnvironment for help.
I am just a beginner on Squeak Smalltalk, please correct me if I make any mistakes on understanding
Generally, requests to this mailing list receive brief responses. If you need more detail, you could try the beginners mailing list. Squeak needs people like to you to increase support for Chinese locales.

The decoding is correct, for example, a chinese character ‘中', the UTF8
decoding is 25185837, but the dispaly in the workspace is ??, I inpsect on : (SimplifiedChineseEnvironment new) isFontAvailable, it return false to me.
and i run following to installFont: (Locale isoLanguage: 'zh') languageEnvironment fontDownload. seems not font support on the net, any suggestion on how could i got the font for chinese?
And also i have read the chinese support codes developed by Yo, it does work on Squeak 3,8 and 3,9, but it doesn't work on 4.1, I don't understanding what the different feature on Squeak4.1 on Language support side?

Find another strange thing
inspect "TextStyle defaultFont", in Squeak 3 (3.8,3.9,3.10), it was display as StrikeFontSet, but in Squeak 4, it was display as StrikeFont.
Also for the inputIntepreter, it work in 3.8, 3.9, but doesn't work in 3.10, any suggestion on how to debug such kind of method?

You need to leave a FontSimplifiedChineseEnvironment.sar in the default directory for Squeak to load it automatically.
Have you seen http://code.google.com/p/chinesesqueak/ ? I can't read Chinese and have no idea of what those forums contain :-( but I did see some posters including the SAR file for Chinese support.
HTH .. Subbu
yes, i have downloaded the codes from svn checkout *http http://chinesesqueak.googlecode.com/svn/*:// chinesesqueak.googlecode.com/svn/ regarding the chinese character, the code is working for Squeak 3.8, and 3.9 but using these codes, 3.10 has problem on typed in chinese character.....
Also for Squeak 4.1 it seems it has been changed much from based, am I right?

This is because of input method conflict between supporting legacy codes and modern UTF-8 input codes across multiple platforms.
See SQ-554 and its discussion in etoys-dev for the background. You can adapt the patch to make it work for your case (Squeak 4 on Windows?).

Thanks Subbu,
This is because of input method conflict between supporting legacy codes
and modern UTF-8 input codes across multiple platforms. Don't very understand about the conflict you mentioned, could you give some example?

See the threads http://lists.squeakland.org/pipermail/etoys-dev/2010-October/005933.html http://forum.world.st/New-Win32-VM-m17n-testers-needed-td63730.html
In a multilingual setting, the language of input codes can be different from what is implied by the locale setting (system language). So one can encounter Chinese input in a Latin-1 locale. The image has methods to switch locales manually but not converters :-(. The logic for arriving at language+encoding is different on different platforms. Part of this logic lies in VM and part of it in the VM. VMs ports on Windows, Mac and Linux use different logic to deal with multi-byte input methods, so the code in the image has to dance around with VM host, locale setting and language codes to collect input.
If you are not likely to read files encoded in pre-Unicode Chinese codes and you are just interested in getting Squeak to deal with Chinese input on Wintel VM, just apply a patch to override all this logic for now. Hopefully, better code will emerge as we get more feedback from Chinese users.

Yes. In my patch, I tried to get UTF-8 encoding thru the VM into Squeak where I could decode uniformly. It worked on Linux VM but not on Win32. I don't have Win32 development machines around, so I couldn't take it further.
