> In investigating a bug for the check "if( str->size() > 65536 )" which should
> be "if( str->size() > 65535 )" in writeString() , I found a couple of other
> problems:
> (1) The OpenwireStringSupport::readString method should read the utf8 length
> as an unsigned short rather than short. The problem is that utf8 encoded
> strings (using writeString) longer than 32768 will become truncated when read
> back using readString().
> (2) The writeString() method should also check the value of utflen after
> determining the UTF8 length of the encoded string, since with the support of
> characters greater than value 127, encodings of 2 UTF8 bytes per byte can
> exist.
