Environment

Windows build number: Microsoft Windows [Version 10.0.18362.175]
Windows Terminal version (if applicable): 0.2.1715.0

Clink version 0.4.9

Hack font

Steps to reproduce

Use clink with cmd.exe within Windows Terminal.

I have a custom lua script for clink that intends to mimic the prompt produced by "powerline" in bash. See https://powerline.readthedocs.io/en/latest/ for information on powerline.

I've attached all of my clink settings and scripts:
clink.zip

Note: This prompt uses characters not included in most fonts (including Consolas). You must use a powerline compatible font (like "Hack" linked above) for correct prompt display.

Expected behavior

I expect the terminal to look somewhat like this (running inside ConEmu):
image

Actual behavior

Instead I get this:

For some reason the size of the terminal as deduced by clink is incorrect and the prompt is wrapped prematurely.

To your credit, Windows Terminal does a better job of color reproduction than ConEmu.
