As that character is a non-spacing modifier, we display it
with a static composition, and a glyph in a static
composition are displayed by a blank rectangle if no font is
available. This is because a hex code makes the resulting
display of composition (several glyphs may occupy a single
column) unreadable.
It may be possible to change the current code to use a hex
code displaying if a composition contains just one glyph and
that glyph has no font, but it may be for 24.2.
