Forums mIRC Help Sending non UTF-8 encoded text from script?

Using mIRC 7.x, I'm having some issues with clients that don't support unicode. I use $chr(160) heavily in my scripts and it now sends \xc2\xa0.

From the script language, is there anyway to force /msg to send a message with no UTF-8 encoding? I disabled "UTF-8 encode/decode messages" from Options->IRC->Messages but it seems to have no effect. As a workaround, I tried using "/raw -n PRIVMSG :<msg>", but that still seems to be sending \xc2\xa0 for $chr(160).

Any ideas? Or is going back to 6.35 my only option?
