=head2 bytes
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.
Is this a C or a perl API ?
Perl.
If a perl API then converting to UTF8 means that substr() is going
to give me a sequence of bytes which encode the string. As such they
have to have the internal UTF8 flag turned off.
=head2 chars
chars_to_utf8(STRING)
The chars in STRING are encoded in-place into UTF-8. The chars are
asssumed to be encodedin ISO 8859-1 (Latin 1) or US-ASCII.
You took my name and used it exactly the opposite way to what I intended.
Maybe my name was not as clear as I thought.
Please take a look at take five:
: chars_to_utf8(STRING, ENCODING[, CHECK])
:
: The chars in STRING encoded in ENCODING are recoded in-place into
: UTF-8. Returns the new size of STRING, or C<undef> if there's a failure.
:
: No assumptions are made on the encoding of the chars. If you want to
: assume that the chars are Unicode and to trap illegal Unicode
: characters, you must use C<from_to('Unicode', ...)>.
:
: [INTERNAL] Also the UTF-8 flag of STRING is turned on.
:
: utf8_to_chars(STRING)
:
: The UTF-8 in STRING is decoded in-place into chars. Returns the new
: size of STRING, or C<undef> if there's a failure.
:
: If the UTF-8 in STRING is malformed C<undef> is returned, and also an
: optional lexical warning (category utf8) is given.
:
: [INTERNAL] The UTF-8 flag of STRING is not checked.
My intent was that STRING is _ANY_ string in perl's internal representation.
The returned string is a sequence of bytes (0..255) which are the
encoding of that string.
