If the "bytes" parameter of get_string and get_utf8_string is negative, the length will be read from the stream instead. The bytes parameter has now a default (-1), allowing to use them directly as reverses of put_string and put_utf8_string . put_string was not implemented, so I implemented it to allow sending ASCII strings (which are much smaller than UTF8 ones).
