[XML-SIG] wstring encode

[Gabor Melis]

Hi

Is there a way to encode a wstring? I looked into wstrop.c but it
seems that the encode method doesn't make it to Python. I can see no 
reason for that, though.

Let's suppose we have encode() for a minute. It is still not good
enough for me, because I want to encode a wstring with a specific
encoding, but using numeric references ({) for characters not
available in the target charset.

It is no big deal, I can implement it, but I'd hate to duplicate
work. Forgive my ignorance, but do we have such a beast implemented?

Cheers, Gabor
