If this affects the glyph string, then fill_XXX_glyph_string is a
better place, yes.

I'm not sure what issue you have in mind.  Why should it matter if the
glyph string's face is ASCII or non-ASCII?  Do you see any problems
related to the box face that happen when text is ASCII, but not when
it's non-ASCII, or vice versa?
