I see and share the uncertainty. But isn't tr-TR.1254 the same as
Turkey_Türkiye.1254? In other words, if we just used the short,
standardized locale names and left the encoding suffixes (with their
potential Frankenstein behavior) as they are now, would the situation
be any worse than it is now? We could forgo using the mutable locale
names and leave the encoding mystery for a better day.
