I have some objection. One should not use PUA codes for internal purposes
in general purpose software. What will happen if people use such software
for manipulating files containing the same characters with some different
user intended meaning?
If only a few internal ones needed, use noncharacters like the ones in
U+FDD0..U+FDEF. If many, use these like surrogates or use codes higher
than U+10FFFF if the application allows.
