Convert UTF8 characters to Hexadecimal

[flashkid]

I want to convert UTF8 characters to Hexadecimal numbers. For example:

if I have a string like:

HI

I want the Hex to be like :

\u0048\u0049

Can this be done?

Thanx

Not great but you should be able to make it work:

my $hex = join(' ', map { sprintf('%lx', ord $_) } split('', 'HI'));
