Yeah, this point has been raised before, and I agree with it.  I
haven't heard anyone who speaks a European language complain about
this, but it seems to keep coming up for Japanese speakers.  I am
guessing that means that using multiple encodings is fairly common in
Japan.  I typically don't run into anything other than UTF-8 and
Latin-1, which are mostly compatible especially if you're an English
speaker, but if it weren't for that happy coincidence I think this
would be quite annoying.
