Although there are some relevant fixes in 4.5, I doubt they are relevant
to what you want to do.

By using the \uNNNN or \UNNNNNNNN syntax. For example, pipe your code
through
perl -pe 'BEGIN { binmode STDIN, ":utf8"; } s/(.)/ord($1) < 128 ? $1 :
sprintf("\\U%08x", ord($1))/ge;'
or similar to convert extended characters to UCNs.
