Rio doesn't handle double-width characters (e.g. CJK characters) #697

When the cursor is on a double-width character, the character shrinks to single width (see screencast)

I found a similar issue that used to be in Alacritty here: https://github.com/alacritty/alacritty/issues/265

Is this regarding the cursor only? I am not sure if I understood correctly (I am unable to watch the video you sent)

@raphamorim Yes it's on macOS. The version is 0.1.10. I just upgraded to 0.1.17, the issue is gone :D
