Right, that was the same case I checked. In C locale, � is not a
letter, so you get the above from the initcap transformation.

Possibly, I haven't checked. If they have any month names with
non-ASCII characters in the middle, they'd see the same thing.
You would certainly also get undesirable results from TMMONTH, since
it wouldn't know how to uppercase �. In my view none of this is
a Postgres bug --- the correct fix is to use locale settings that
correspond to the behavior you want.
