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.
