[sfnt] Better PS name handling ( #54629 ).
...
* src/sfnt/sfdriver (IS_WIN, IS_APPLE): Omit language ID checks.
(get_win_string, get_apple_string): Return NULL when the PostScript
font name characters is not according to specification.
(get_win_string): Make trace output work if the high byte if
non-zero.
(sfnt_get_var_ps_name, sfnt_get_ps_name): Previously we preferred
Win PS name (when there is also an Apple PS name); change this into
a fallback to Apple PS name in case the Win PS name is invalid.
