You mentioned you were unable to find the updated (2008) Liberation font family with a slashed zero. I found a version with a dotted zero tonight via a Google search for "Liberation Mono" which yielded a first item entitled "Liberation fonts" (http://en.wikipedia.org/wiki/Liberation_fonts). This appears to be the Wikipedia page you mentioned above in the body of your article, as it has the quote re "The fonts were developed by Steve Matteson of Ascender Corp....licensed by Red Hat, Inc. as the Liberation font family."
The current version of that Wikipedia page states "The Fedora Project, as of version 9, features slightly revised versions of the Liberation fonts contributed by Ascender. These include a slashed zero and various changes made for the benefit of internationalization." At the bottom of the page there is a link to the "Liberation Fonts project at Fedora Hosted" (https://fedorahosted.org/liberation-fonts/).
In the zip file you link to, the bold, bold italic, and italic mono fonts are version 1.04, and have a dotted zero. However, the regular Liberation mono font (LiberationMono-Regular.ttf) is version 1.00, and is not dotted.
When programs need to display lots of data in a very small space, tiny fonts (e.g. in the range of 4x6 to 6x10) can be extremely useful. Unfortunately, .net does not allow the use of bitmap fonts in its controls, and all the TrueType fonts I've seen become illegible at such sizes.
Other than having a program manually draw characters as bitmap graphics, is there any good way to show data legibly at such sizes? For example, do there exist any TrueType fonts that scale well to such sizes, or is there any utility which can take a collection of bitmaps and produce a TrueType font which, when rendered at a particular size, will yield those bitmaps precisely?
Note that for legibility at 4x6, it's necessary that some font characters be rendered quite differently from how they would normally appear at larger sizes. An "N", for example, should appear as a taller version of "n".
I'll give those a try. ProFontWindows brings back some memories, since I looked at ProFont in my Macintosh days and ended up creating something that was similar but a bit different. Most notably, the font I created made most of the lowercase letters four pixels wide instead of five and used a narrow zero instead of a slashed one. I actually replaced Monaco-9 with my own adaptation, so it would be the default monospaced system font.
Proggy-Tiny looks like it will be pretty good for use in a 6x9 character box. ProFont is unfortunately only a bitmap font, and thus is not usable in .net controls. Maybe I'll just have to kludge together some bitmap routines for use with a 4x6 character matrix.
Akkurat looks pretty appealing, but $US150
I also tried some "programmer's" fonts but they are more stylish than readable, and for my taste Courier New lacks the vertical.
The CodeProject font top-list ranking is well-deserved, Consolas is really the best ClearType font (my thumbs-up) and Lucida Console is the best CRT display font.
