    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}".

We could support this form, as well as \u and \U for compatibility
with other languages.
