Do you know why 0xDF and >0xFF were excluded before ? For speed maybe ?
Anyway, thanks, applied as a6f87d8c282ba94b0308898be052d1ac956d0ea9

Actually, it was <=FF that was excluded except for DF. It could have
been for speed; or that when user defined case mappings were added, this
spot was overlooked.

The comment in the patch context explains.

\xDF is the only code point < 256 that folds to a multi-codepoint sequence.

There are many such codepoints>255.
