Basically not just chinese characters.
I want scite to be able to display anything, japanese, korean, chinese. Anything. I can display that with notepad. Why I can't display that with scite?
SciTE v2.23 on Windows seems to work fine with these character sets for me. Have you set the encoding to UTF-8?
According to the SciTE documentation section on Encoding:
SciTE will automatically detect the encoding scheme used for Unicode files that start with a Byte Order Mark (BOM). The UTF-8 and UTF-16 encodings are recognised including both Little Endian and Big Endian variants of UTF-16. UTF-8 files will also be recognised when they contain a coding cookie on one of the first two lines. A coding cookie looks similar to "coding: utf-8" ("coding" followed by ':' or '=', optional whitespace, optional quote, "utf-8") and is normally contained in a comment.
