Sorry it took me so long to answer this.

It might be presentation-only. Or in other words, in the future I should
probably refresh my memory before shooting off at the mouth.

Yeah, probably, although for the general case note that you still need
to know the locale of all the inputs *and* the context they're going
into.

I don't understand what you're getting at here. I must've missed
something earlier in the conversation.

I suspect that you misunderstood the point of this feature. It's for
people who don't care about internationalization; they just want the
compiler to recognize local conventions when processing comments,
identifier names, etc. For example, some Turkish programmer writes a
program in Scheme + Turkish, he sets his Scheme compiler to "Turkish"
mode, and it just works. Of course, it won't work if he e-mails the
program to his friend in Germany, but he doesn't care, because he
doesn't plan to mail it around the world.

The standard XML-style prologue is what you use when you want to use a
local encoding/language *and* make it portable. If you don't care about
portability, just flip the compiler switch that says, "Follow my local
conventions, instead of English or language-neutral conventions."
