Hello,

The raccoon glyph shows visually in the web browser but does not inside graphical gnu emacs.

  character: 🦝 (displayed as 🦝) (codepoint 129437, #o374635, #x1f99d)

Steps to reproduce behavior

 1. start, emacs -Q --init-dir=/tmp/xxx
 2. enter, the following one line in the file /tmp/example.html

<pre>🦝</pre>

Expected behavior, the glyph presented in the web browser is shown in emacs.

See attached picture of raccoon glyph in emacs and web browser.
