Re: Font support of UTF-8 chars differ between w32 Emacs and Cygwin Emacs

Any idea why such differences?

Best regards,


I've had a chance to look at this now, and it doesn't seem to have anything to do with emacs.

I've created a text file 25b7.txt (attached) with a single line containing the white right-pointing-triangle. When I issue the command "cat 25b7.txt" in a mintty terminal, I sometimes see an empty rectangle (meaning the character can't be displayed), and I sometimes see the white right-pointing triangle, depending on which font I select in the mintty options.

I don't know enough about fonts and UTF-8 encoding to be able to shed any more light on this. Maybe someone else can help.
