Message:

Editor: Check if mb_strtolower exists before using it in the font library.

Prevents an error when uploading fonts on certain systems, because the mbstring extension can be missing and thus the function may not be available.

Props mujuonly, swissspidy, peterwilsoncc.
Fixes #60823.
See #55603.
