commit 99de4076f97c39f53872307c631164f4bf8fffdd
Author: Joseph Wright <joseph.wright at morningstar2.co.uk>
Date:   Mon Nov 9 10:52:55 2015 +0000

    Use \tex_lowercase:D in l3regex
    
    At soem future stage it may be possible to use
    \char_generate:nn here (this depends on engine requirement
    updates for XeTeX). However, for performance reasons
    it may well be desirable to stick to this lowest-level
    approach.
