 * Something seems to be worth looking at (with PHP 7.3):
 * preg_replace(): Compilation failed: escape sequence is invalid in character class
   at offset 4 in […] plugins/wp-typography/includes/wp-typography/components/class-
   public-interface.php on line 307′

 * [@detrax](https://wordpress.org/support/users/detrax/) Thank you for the bug 
   report. Which versions of wp-Typography and PHP 7.3 are you using exactly?

 * They are those two:
 * PHP: PHP 7.3.7
    wp-typography : Version 5.5.4

 * Thank you. I’ve not been able to replicate that error on my own installation 
   of PHP 7.3.7, but from looking at the regular expressions it seems it might have
   always been incorrect, but the syntax issue only pops up with PCRE2 as used by
   PHP 7.3. (And the exact behavior might also depend on some system library version.)
 * I’ll look into it tonight.

 * Thanks for your quick answer. If I might be of any assistance (eg. test), let
   me know.
