This is exactly what I was going to say, and that one big issue I had when experimenting with ligatures for Hylang (a dialect of LISP) was that it did not keep the spacing of the original character combinations. While I thought the ligatures were much more concise, when they were disabled it shifted things around which ruined the indentation. It made the code ugly and hard to read for anyone not using them, so I had to give them up.

Hopefully one day we can all have language specific characters that make our code more concise. Until then I'll stick to fonts that keep the spacing of the original intact.
