My understanding of UTF-8 is that some characters require multiple 
octets to represent so it is not so simple as simply assuming that 
strings are UTF-8.  The library needs to be prepared to handle UTF-8 
internally if it does any string parsing.  It needs to know for sure 
if the string is UTF-8.  Some existing strings may use extended 
characters (in the system's native character set) but not UTF-8.
