Wrong width for flag symbols

Open abrander opened this issue 4 years ago • 4 comments

runewidth.StringWidth(🇩🇰) returns 2.

I haven't looked into this at all, and I have no idea what I should expect, but a width of 1 seems reasonable.

The problem, as described in the video, is that it's technically 2 characters, with the renderer collapsing it to 1 character. So I think it's ill advised to change it from 2 to one, as it would break any renderer that doesn't support flag emojis.

Looking at this in a bit more detail, I think the flag symbols need special handling in the renderer.

However, they definitely count as emoji, and should be displayed using the Emoji Presentation property.
