* admin/unidata/emoji-zwj.awk: Avoid sprint buffer overflow
Some AWK implementations have a fixed buffer for sprintf; for mawk the
default size is 8192 bytes. Hoist a string concatenation from
a sprintf call to avoid running into that limit. See discussion at
https://lists.gnu.org/archive/html/emacs-devel/2023-06/msg00090.html .
