I'm a Textmate n00b, so maybe there is just something I have misconfigured, but just in case it is a bug...
I noticed today that I wasn't seeing quotes correctly in comments at my default settings. My default font is Monaco 12 pt. Anti-aliasing is off. Inside of comments which are italicized, I noticed that I don't see single quotes at all (just a space) and double quotes as single quotes. This problem doesn't happen in the non-italicized code text and goes away in italicized text if I boost the text size to 14 pt. It also goes away if I turn off the italics styling on comments.
So is there something I need to tweak to get quotes looking right in the italicized text?
I checked TextEdit for comparison with antialiasing turned off in the System Preferences for 12 pt and lower, and the quotes in Monaco are normal there.
