Re: Summary of Unicode/language features in Mac OS X 10.2 "Jaguar"

Since you're dealing with Polytonic Greek, I suppose your original file
is a plain text Unicode.

First of all, the issue with TextEdit showing GB 18030 over Unicode
seems to be a bug in the application.
The logic here is simply selecting a character encoding that can
represent all the characters in the document.
It should always select Unicode over GB 18030 for user's sake.
If GB 18030 annoys you much, you can remove the encoding from the menu.

For the mixed-font selection. The Cocoa Text System tries very hard to
"honor" the original font user selected. In this case opened from a
plain text file, the font is Monaco (you can change the setting in
TextEdit's preference panel). From there, Cocoa looks for the font
character by character preferring the system supplied fonts. As you
discovered, you can always change the font and save as rich text that
preserves the font setting.
