What is "this encoding" called? The article you link to describes a 
specification, not an encoding.

What makes you think that you should be able to convert arbitrary text to 
strings suitable for use as ID or NAME tokens?

What would you expect this encoding to do with these strings?

"1234"
"?*(#@!+{})"
"          "
