Sorry to be blunt, but that's silly. If you need a special-purpose
"character" (a code-sequence, to be more precise) for use within your
specialised application, use one of FDD0..FDEF, FFFE, FFFF, 1FFFE, 1FFFF,
2FFFE... 10FFFE, 10FFFF. They are non-characters available for exactly
this use.
If you need real character sequences for markup, there's this thing called
XML. Perhaps you've heard of it. It's worth taking a look at; I think it
really might catch on some day.

I believe the answer is stated within that document. You're on the right
track, but I'd still encourage you to read the document.
