Comment:

 In [changeset:"57865" 57865]:
 {{{
 #!CommitTicketReference repository="" revision="57865"
 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.
