Are there reasons not to use Perl's notation for Unicode characters,
i.e. "\x{...}"?  The Unicode code for the desired character,
is placed in the braces in hexadecimal, and has no fixed length.
Examples: "\x{DF}", "\x{0448}", "\x{001D0ED}".

I think this notation is well suitable for Emacs, because \x{...}
indicates that a hexadecimal value is expected in the braces.
And in the Unicode branch it will be just another way to specify
a hexadecimal value with a variable length.
