I just heard an interesting program on "Fighting for Authentic Design":
http://www.abc.net.au/rn/bydesign/stories/2010/3087247.htm
Some of the links on my page were broken. Does anyone know what has happened to the excellent screenfonts.ca site?
I have also added Courier to Courier New comparison.
While font issues aren't exactly specific to Cocoa, this is an issue that should be much more widely known about, especially among developers. But I also have the question about which fonts are officially sanctioned by Apple to use?

The code I'm trying to write needs to pad one string with spaces so that certain characters line up visually with selected characters in a different string (within a view). It seemed like a relatively easy task as long as I could require the use of a monospaced font. However, it comes out looking various kinds of wrong depending on how many spaces I add. I've tried this with a number of Courier variants with the same result.

(Also, that there may not be a neat and obvious formula for how to compensate.) Are these results reproducible? Was a fixed-size character width a bad assumption? Or is it a bug?
