Chrome notifications do not work well with colors. The notification is given without being HTML-ified like in OmnomIRC, so colors (and presumably use of bold and underlining) don't work. (For colors, for example, there's a \x03 for every color change, including also the color code.)

Hm. I'm using a Firefox extension, so let me try it in Chrome.
Edit: Nope, doesn't work in Chrome either. It doesn't display the non-printable characters, but the color code is still there.

No colors is fine. I just don't want the color codes or the special character used to indicate a color change (same thing for bold and underline).
