#19 Yanking unicode strings

[Henrik Ekelund]

When yanking unicode strings, the unicode characters
are almost formated as python expects it but not quite.
A unicode character is converted to a string such as
\x{00E5} , but the curly brackets shouldn't be there
and it should be a u insted of an x. The correct syntax
is \u00E5 . Is there a way to change this?
