Right it's the Iosevka font, https://github.com/be5invis/Iosevka
Is it to posible to add this type of ligatures?

Hmm.. I'm not sure how Iosevka does that. I'll have to download it and check it out.

However, I have fixed the repeating ligature problem in the branch features/contextsubst. Look at issue #37 for more info. Instead of getting partial ligatures, it simply reverts to the normal characters after it exceeds the longest version.

@kiliman
Iosevka substitutes one hyphen - in to a part of that arrow.
For <---------- a Chaining Contextual Substitution is used.
For ----------> a Reverse Chaining Contextual Single Substitution is used.
