Proportional fonts for coding: vocabulary

Hi all.
Recently I’ve switched to proportional fonts for programming, and have been looking for font choices, but find I’m missing some vocabulary.

There was a post on variable width fonts for coding here:
But aside from a few choices, I couldn't glean how to look for good fonts.

Here are the characteristics I’m looking for:
0 - The font needs to work well at small sizes and coarse resolutions.
1 - The lowercase L and number 1, as well as capital i, need to be distinct at small sizes. Same with zero and o (upper and lowercase).
2 - Punctuation needs to be prominent. A period and a comma mustn’t be confused. Same with primes and hatches. (Helvetica and Fira Sans crash and burn here).

Open Type for noobs


Hello! Someone in here can help me with Glyphs?? I'm adding the small caps to my font, but actually it's the first time i do this so (this is also my first font), I'm having some troubles: InDesign doesn't make the change of letters when I use the Small Caps button, just from the OpenType window and it works only on the capital letters; and, I dont know neither how to set the case sensitive signs in open type what suffix do I need to put on my glyphs and which Open Type function works for that?
I hope someone can help me with this problem greetings from Mexico!

Programming OpenType Font with FontLab 5 to have size restrictions


Does anyone know how to set some parameters that restrict a font to specific sizes? In my case, I need the character to be no smaller than 12pt and no bigger than 72pt. I would like the character to change to another character for sizes smaller than 12pt or bigger than 72pt.

Is this sort of thing possible in FontLab 5 with the OpenType programming panel?


OT How-To

Indices : “How To” Section : Programming OpenType Features

OpenType is a powerful new font format that gives users a much broader range of typographic and linguistic control than has previously been available with a single digital font. More and more type Foundries offer OpenType (OT) fonts these days and one can expect the average user to become more aware of the benefits of OT fonts as more applications take advantage of their capabilites in the future.
