I am using a GUI control that supports only 1 font. I'd like to find a single font file that combines TeX's main font's plain, bold, italic, and bold-italic font in one font file for use with that GUI control.
So for instance, characters 32-127 are plain, 128-191 are bold, etc.
Does such a thing exist anywhere?
(Note, this is for English-only text, and not Unicode obviously.)
