bug#13423: 24.1; Can't display (some) characters outside BMP

[Michael Norrish]

This bug report will be sent to the Bug-GNU-Emacs mailing list
and the GNU bug tracker at debbugs.gnu.org.  Please check that
the From: line contains a valid email address.  After a delay of up
to one day, you should receive an acknowledgement at that address.

Please write in English if possible, as the Emacs maintainers
usually do not have translators for other languages.

Please describe exactly what actions triggered the bug, and
the precise symptoms of the bug.  If you can, give a recipe
starting from `emacs -Q':

The following text (featuring character U+1D54C), doesn't display the
SMP char

  ``𝕌(:num) ≼ 𝕌(:'a ucinf)``,

even after doing

  (set-fontset-font t 'unicode-smp "STIXGeneral")

The character viewer on the Mac confirms that this font is in the system
and has a glyph for that character code.

If Emacs crashed, and you have the Emacs process in the gdb debugger,
please include the output from the following gdb commands:
    `bt full' and `xbacktrace'.
For information about debugging Emacs, please read the file
/Applications/Emacs.app/Contents/Resources/etc/DEBUG.

Can you check in a recent version and let us know if it's still a
problem?

Indeed, the text displays fine on 24.4.1 on OSX 10.11.4.
