If you want to do it in Fontlab, you'll need to have a typeface with underlines built in. In InDesign you can apply character styles with a underline, defining its offset, stroke weight, colour etc. For the gaps you just omit the style for that specific character. You can also play with adding a thin white stroke to the font to make gaps.

Why not using GREP styles in Indesign?

1. Set up a Paragraph style for your text.
2. Create a new character style for the underlining.
3. In your paragraph style add a nested style and call the created character style.
4. Click on GREP style in your paragraph style and add a new GREP style.
5. Enter the character you want to change (p or g etc).
6. Where it says Apply Style create a new character style with underline turned off (or stroke around text).
7. Apply paragraph style to text.

I'm sure there is an easier way, but can't think of anything else without testing it.

> Eike Dingler has implemented an interesting underlining feature

Describe?

I'm interested in this thread because some scripts (like Armenian) have a much more serious problem than Latin in terms of underlining destroying legibility.
