Decodes the passed String into hex. Invalid hex values will be discarded.
result = DecodeHex (s)
|result||String||The passed string decoded into a hex string.|
|s||String||The string to be decoded into hex.|
Hexadecimal encoded strings are byte-based instead of character-based, i.e. they ignore text encodings. For example, the string "Xojo™" is 12 characters long but, as it uses UTF-8 as encoding, it is 14 bytes long (the ™ character uses 3 bytes in UTF-8). You should keep that in mind when using EncodeHex and DecodeHex.
Only a hexadecimal string made from a UTF-8 string will be transformed back properly by DecodeHex.
The following converts a hex string back into a letter.
