Currently, tmux does not render emoji from Unicode 15 (e.g. U+1FABF 🪿), because the
`wcwidth` function from glibc does not know about the new characters.
Support was added upstream but not released yet
(https://sourceware.org/git/?p=glibc.git;a=commit;h=7fe6734d28feb18acb3c50b13a5f5a52f66d39cf).
Instead, tmux can use the `wcwidth` function from utf8proc, which has
regular updates so that we don't have to wait 6 months for the new
characters to be supported.
