Take (xft) font(s) into consideration? about wcwidth

[fornwall]

Sorry for the late reply!

There are a lot of implementations of wcwidth(): this one, wcwidth in python, gnulib, glibc, wcwidth in nodejs, wcwidth in ruby, wcwidth in lua. utf8proc is getting more popular where people are using utf8proc_charwidth(c) (example), and so on.

Using something along your proposal wouldn't work with these freestanding implementations and is fragile and hard to work across e.g. ssh sessions across systems.

I think we need to standardise the width of code points (including private plane ones when necessary) in fonts intended to be used in terminals as well as possible, and then push out that to various wcwidth implementations.

I've created hack for rxvt-unicode to inject a wcwidth(3) callback using LD_PRELOAD into clients. Works surprisingly well.. ;)

Here is some discussion / ideas to make shells (Zsh in this case) behave better: http://www.zsh.org/mla/workers/2016/msg02326.html.
