bytes_to_utf8(STRING)
The bytes in STRING are encoded in-place into UTF-8. Returns the new
size of STRING, or undef if there's a failure. [INTERNAL] Also the
UTF-8 flag is turned on.
Just to give another example in case my previous mail wasn't clear: Marking
the setting of the utf-8-string as [INTERNAL] (== might change) makes this
function 100% useless, since it is the same as saying:
"might return something represented internally as utf-8, but how perl
treats this scalar is undefined".
(Also: what is the size of a string???)
The above can be applied to all other functions as well: It is crucial
to know how perl treats your character data. I know that, at the moment,
perl sometimes treats scalars as bytes and sometimes as utf-8, with wild
re-encodings going on, but I really _hope_ that all of these are regarded
as bugs.
is_utf8(STRING [, STRICT])
[INTERNAL]
Oh, a function for gururs only....

on_utf8(STRING)
BTW, I would appreciate utf8_on instead of on_utf8, because:
- it's the same as the C API. They should be the same.
- Convert::Scalar uses utf8_on (a weak reason)
- on_utf8 is a question, utf8_on is a command.
