Font Fatigue: Terminal Madness
If you never use the Terminal application in Mac OS X, don't bother reading this. I happen to like Unix, so I'm always using the Terminal. Strange things happen if you have the Terminal's font set to Monaco (the default), but don't have the Mac OS X version of Monaco active. Take a look at Figure 1.
The top line was displayed when only the Mac OS 9 version of Monaco was active (in the Classic Fonts folder). Notice how the combination "l/" has turned into a bizarre character. The bottom line shows how this should look. It only looks this way when the Mac OS X version of Monaco is active. So beware.
