If you can deal with a string that's a bit longer, you could 
base64-encode the MD5 digest:

  put base64Encode(md5Digest(tMyString))

That'll result in a string using only a relatively small subset of ASCII 
characters, leaving most common delimiters (commas, tabs, etc.) free for 
you to use however you like.
