[James Tursa]

This function has several problems, hence the low rating.

- No help included
- No first help line
- Does not do *any* argument checking
- Does not allow for uppercase hex characters
- Does not allow for arrays of character strings as input

If you pass this function some invalid text like 'garbage', it will happily give you an answer with no warning whatsoever that your input is junk. Or if you pass it an array like ['abc';'def'], it will not process the 2nd line.
