Again, I think the interoperability by bitmap capture of the GUI window
should be fully adequate for this application. It is even better, as the
bitmap preserves exactly the glyph shapes in the documentation and will
not cause any potentially confusing unification differences in the
printed material.

Manuals for terminal emulators are a fairly small market segment that is
better covered better by the graphics inclusion mechanisms of word
processor software that also have to take care of coorporate logos, and
other highly specialized non-Unicode symbols.
