Documentation:
Abnormal hook for determining the set of glyphs in a face.
Each function in this hook is called in turn, unless one of them
returns non-nil. Each function is called with a single argument
FACE. If it can determine the set of glyphs representable by
FACE, it must set the variable `nxml-glyph-set' and return
non-nil. Otherwise, it must return nil.

The constants `nxml-ascii-glyph-set', `nxml-latin1-glyph-set',
`nxml-misc-fixed-1-glyph-set', `nxml-misc-fixed-2-glyph-set',
`nxml-misc-fixed-3-glyph-set' and `nxml-wgl4-glyph-set' are
predefined for use by `nxml-glyph-set-functions'.
