Fortunately David Rowley is able to repro this on his Windows box (it
fails even with strings that are succeeding on the other BF machines),
so we have something to work with. The name mangling that is done in
get_iso_localename() looks pretty interesting... It does feel a bit
like there is some other hidden environmental factor or setting here,
because commit 352f6f2df60 tested OK on Juan Jose's machine too.
Hopefully more soon.
