This isn't a very good solution (and it'll only work on X11):
You can determine which font Emacs will use with `internal-char-font'.
You could then call
xlsfonts -lll -fn FONT
and parse the output to get the font metrics. If the metrics for a
particular code point contains all zeros, say
0x009f (159) 0 0 0 0 0 0x0000 .
then the glyph doesn't exist in this font.
