Help converting Hex UTF-8 bytes to character

[Paul Dupuis]

As a general approach:

1) use offset() looking for "\x" (or you could use regex) to find the start
2) if the value returned by offset is not zero (call it tOS) put char
tOS+2 to tOS+2 into tByte1 and char tOS+6 to tOS+7 into byte2 to get the
2 hex values
3) use the formula put
baseConvert(byte1,16,10)*256+baseconvert(byte2,16,10) into tCodePoint
4) lastly put numToCodepoint(tCodePoint) into char tOS to tOS+7 of the
original string

Off the top of my head and (obviously) not tested.
