Encoding conversion patch

[Alexander Kolov]

I wrote a small patch to use different encodings on different ports, but it
has one major bug: in send.c, when string is put into send buffer it
sometimes has some garbage at end, but converted string don't, so I can't
calculate valid len value and it corrupts messages.
Any ideas how to fix that, and if possible, other bugs?
