Code2001 contains some Old Persian glyphs (or so they look, to my 
ignorant eye), encoded at U+F0300 and upwards (i.e., Plane 15 
supplemental private use codes). Note that to access them via character 
codes in XeTeX using the \char or ^^^^ notations, you'd have to give 
the two UTF-16 surrogate values (as XeTeX deals with UTF-16 codes); 
thus, the following test should display the glyphs for you:

(Some of these character code positions are empty.)

If you create a source document containing these characters, and save 
it as UTF-8, I believe XeTeX should handle them just like any other 
Unicode values, though I haven't tried that personally.

Note that the characters available in Code2001 don't appear to exactly 
match the collection which is in the pipeline for addition to 
Unicode/ISO 10646. I'm guessing it is based on an earlier version of 
the Old Persian proposal than was ultimately accepted for encoding. So 
you need to be just as wary of encoding data using these characters as 
any other non-standard inventory.
