Hi David. Thanks for the quick responses.

On closer inspection of the source, I see that the "unescape"

Yea more or less. "%u00b0" for example.
and it will correctly set the utf8 flag
Not AFAICT:
DB<1> x Encode::is_utf8(CGI::Util::unescape("%u00b0"))
0 ''
Perhaps it might be time to add an optional argument to "escape",
Is %uXXXX officially sanctioned somewhere?
An optional argument is good. But if the scalar passed to escape()
has the utf8 flag set it seems to me we could "do the right thing"
automatically.
