bug#65138: 29.1; Problems with Emojis C-x 8 e e

[Robert Thorpe]

The new Emoji system started with 'C-x 8 e e' doesn't work in a sensible
way if you don't have fonts installed for every Emoji.

For example, let's say you pick the category "e emotions".  If none of
your fontsets have the relevant Emoji's then the result is
confusing. The minibuffer becomes two lines high - but it is blank and
displays nothing at all.  There's no message to tell you that you don't
have the fonts installed and that's the problem.  I only found that out
by trial-and-error.  If you press any key at all then you're given
an error.

> Unbound suffix '1': (Use 'C-g' to abort, '?' for help)

Aborting with C-g works.  However, '?' does not supply help.  It gives
the error 'Error in post-command-hook (transient--post-command): (error
"Invalid search bound (wrong side of point)")'.
