#6 Error parsing UTF8

[PerErikA]

When an UTF8 character is found last in the
rawReadBuffer the method getNextUtf8Byte read the
next character direct from the stream. The problem is
that it reads an integer (4 bytes) instead of one byte,
and then discards the extra 3 bytes.

The fix is to make a new variable in
TXMLParser.getNextUtf8Byte (i.e. bVal: Byte) and
change the stream reading to
c:= stream.read(bVal, sizeOf(bVal));
val := bVal;
