Returns the passed String as hex values with the option of separating each hex value in the result with a space.
result=EncodeHex (s, insertSpaces = False)
|result||String||The passed string as a series of Hex values.|
|s||String||The string to be encoded into hex.|
|insertSpaces||Boolean||If True, each hex value in result will be separated by a space. The default is False.|
Hexadecimal encoded strings are byte-based instead of character-based, i.e. they ignore text encodings. For example, the string "Xojo™" is 5 characters long but, as it uses UTF-8 as encoding, it is 7 bytes long (the ™ character uses 3 bytes in UTF-8). You should keep that in mind when using EncodeHex and DecodeHex.
Generate a hex string without spaces:
s = EncodeHex("The cake is a lie.", False)
// s is "5468652063616B652069732061206C69652E"
