$chr(160)
i know its probably not a great idea to use it, but it works perfectly as a space for me. You can have as many as you want.
Every $chr(160) counts as one space.
So:
blah $chr(160) blah
will give
blah(3 spaces)blah
if you just want 2 spaces, you can do
blah $+ $chr(160) blah
remember to turn OFF/uncheck SJIS/JIS conversion in IRC/Messages else it'll crash mIRC 6.15
