Arbitrary-length arrows

[be5invis]

To support LONG arrows like <----------------------- and ---------------------->
The current Iosevka implementation is:

Leftward : A chaining substitution like sub hyphen.cont hyphen' by hyphen.cont
Rightward : A Reverse Chained Single Substitution table like reversesub hyphen' hyphen.cont by hyphen.cont. See here.

NOTE: FontForge cannot export Reverse Subs.

it’s actually not a bad idea

This is it in action for reference (Coq language variant in Iosevka):

And currently in FiraCode (ofc a few of the top 2 rows isn't possible until there's language flavoured variants)

Sorry, don't know why I didn't specify the font originally. It's Losevka's Iosevka's ligatures: https://github.com/be5invis/Iosevka/blob/master/README.md#ligations

Thanks! I checked it but missed the point that not all arrows are enabled by default. Also double arrows looked differently in 2017.

BTW it’s iosevka, not Losevka (although I was wondering the same question every time I saw the name. I went and checked to be sure just now. The importance of using the proper font :)

The downside of most repositories being all-lowercase and I being identical to l 😞
