Window titles not interpreted according to current charset

[Jellyfrog]

Simple test:

echo -ne "\033]0;åäö\007"
Result: åäö
Expected: åäö

TERM=xterm
SHELL=/bin/bash
LANG=en_US.UTF-8
LANGUAGE=en_US:en

PuTTY set to UTF-8
If set inside PuTTY config, it displays correctly.

Found this:

If an escape sequence (e.g. OSC 0) sets the window title bar, the text in the escape >sequence is just sent to the window system for display. We should make sure it is >interpreted according to whatever character set / codepage the terminal emulator is >currently using.

For instance, when charset is set to UTF-8 from PuTTY and locales on the remote >computer are en_US.UTF-8, unicode characters are shown as they vere latin chars.

That seems to fix it; code's not great; see the commit message.

Cool!
I'll compile tomorrow and try :)

Now it works fine! Thanks!

Note to self: the commit message in the third commit, "GH-88: Actually use the terminal encoding for the title" is informative: 6fd9b21

Seems to be broken completely if PuTTY and remote computer are set to ISO-8859-15, window title is blank after login and changing screens or other screen commands won't set the title as they did before. With UTF-8 it is working fine.
