It also assumes a pretty strict set of expected characters: If you
don't have UTF-8, you have:
[byte-order-mark] "<?xml " [version-spec] [encoding-spec]
Basically, the encoding can be discovered very easily given an
assumption about legal content. Once that assumption doesn't hold,
the encoding can't be discovered reliably.
We could probably make a pretty reasonable statement of how to
auto-detect enough so that Python files could have an encoded
declaration (however we spell it), but it's hard to beat the
assumption of mandated structure. (Some assumption, huh? ;)
