Actually, I don't represent the ligatures themselves in modern character sets. I transcribe them into the set of characters they represent. In the end, everything ends up in standard Latin or Greek Unicode. It is theoretically possible to design fonts that convert sequences of characters into ligatures that look like the scribal abbreviations, but I see no value in that. The point is to make the material accessible and searchable in electronic form, not to create a one-to-one facsimile.
