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?
For InputIntepreter

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.
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?
