Support for numeric character reference for workspace names

[Leinnan]

In i3(or at least i3-gaps version) we have support for this characters(example[with spaces, because github replace code with one char just like i3bar]: & # x0C8D;), which are great when we using icon fonts like font awesome. In sway we have just plain text. Any chance for support that?

I guess we should implement that to support i3 compatability, but ftr I disagree with the feature. Why not just output unicode characters?

Unicode characters can be difficult to type. This is especially when working with icon fonts which make use of otherwise unused code points which won't show up in any physical or soft keyboards.

Plus months or years later when you want to tweak your bar script, you end up looking at a bunch of unknown character boxes. You can at least look up a code point in a reference. It's impossible to tell what a little box was supposed to be.

But you can use i.e. \u

Ah, I was confusing this for any character substitution. Then I've got no clue.
