[jdev] Get the length of the utf-8 sequence in Java

Hi list!


Is there a better way in Java to get the length in bytes of an UTF-8
sequence of a string, than to just convert it to a byte array and check
the arrays length? I have to validate JIDs which are only allowed to
have 1023 byte UTF-8 strings for each portion. I have not found an
elegant way to do this in Java as length of the string returns the
number of characters in a string and not the number of bytes in its
UTF-8 representation.
