I'm a Taiwanese. I use linux,windows.  On linux, the default coding locale is zh_TW.utf-8.  It works well for fossil. But on windows, the default command line code page is 'cp950'(big5).  So, if I write comment, I must call my comment editor 'notepad2' to force write out utf8 comment. The utf8 comment display well on 'fossil ui' web page.  But, on cmd console which windows provide, it can only display big5.

So, I suggest on windows, fossil should convert code page when display comment and check-in comment.

I think this issue should also happen on check Chinese file name.
