The real problem with charsets and encodings is, that you always have to tell
the interpreting program (Browser, Mail/News reader, ... whichever program
wants to show the bits from the net in a readable form) which Charset (and
encoding) has actually been used to encode the message, so that it can choose
the matching decoder.
If this information is not given, there is no other way than guessing. And
everybody knows that computers are not good at that. How would a computer know
how the string 'äëïöüñ' from James should actually look like, if he hadn't had
specified the encoding in the header (open the source code of his mail, and you
will see the following line: Content-Type: text/plain; charset="iso-8859-1").
The computer could then (for example) have guessed that those bits were
supposed to mean "潆秭" ("eddy billion" in Chinese)... Ok, I admit, I cheated a
bit on this one - it wouldn't have been a valid bit sequence for a GBK decoder,
which any sane guessing algorithm would have detected... but still, I think you
get the point.
So, people, use Unicode (the "universal charset") encoded as UTF-8 for
everything - and maybe in a few years we can all forget about all this
charset/encoding mess :)
Patrick.
P.S.: I used Unicode/UTF-8 in this mail (and of course it's specified in the
mail's header), otherwise it wouldn't even have been possible to put both
Chinese characters and umlauts in one mail.
