It's actually only lower case.  (It should really be casefold, but that 
might be a separate project for another day.)  But after reading this a 
few times, just writing "for converting to lower case" led me to ask 
"but what about upper case", so I reworded it to "case conversion".

There is the "builtin" provider, and it is affected by this as well.
