It seems that the most widely used symbol for Bitcoin is a B with two vertical lines through it¹. It makes sense, as a single letter with a line or two through it is common for many currencies. Is there a plain text printing for this symbol, or perhaps a font that can insert it into documents and the like? What about a hex code or something for HTML printing? I'm looking for other ways to denote the currency without using an image.

1. With the symbols found here, it looks like a circle around it might become part of the official symbol as well. Maybe I should ask that separately.
