Color Blocks shifting when using powerline enabled fonts

[Cornelicorn]

Environment

Microsoft Windows [Version 10.0.18362.388]
Windows Terminal (Preview) 0.5.2762.0

tmux zsh (bullet-train theme) on Ubuntu WSL 18.04.3 LTS

Steps to reproduce

Install tmux or zsh and install a theme with color blocks (e.g. bullet-train theme) and configure a powerline-font in Windows Terminal.

Expected behavior

Font used for startup does not matter.

Actual behavior

If you start zsh/tmux with a Powerline font, all color blocks are shifted slighty:

If you start with a non-powerline font (e.g. Consolas) the blocks are the correct position:

Applying the powerline font after startup works as it should:

Using WSL without the Terminal App works (excpept lacking Emoji support)

Temporary fix:

save this script:

#!/bin/bash -e

# Replace the powerline font with the Consolas font
function shutdown {
sed -i '/"fontFace" : "YOUR_CUSTOM_FONT",/c\"fontFace" : "Consolas",' /mnt/YOUR_CUSTOM_PATH/profiles.json
}

trap shutdown EXIT #Execute function shutdown when terminal exits
#Start Tmux (change to bash/zsh/...)
tmux

And change the commandline option in profiles.json to start it. (e.g. "commandline" : "wsl.exe -d Ubuntu-18.04 /home/user/.zsh_startup",

Then add sed -i '/"fontFace" : "Consolas",/c\"fontFace" : "YOUR_CUSTOM_FONT",' /mnt/YOUR_CUSTOM_PATH/profiles.json at the end of the rc file of your shell (e.g. ~/.zshrc)

This way the font will be loaded after your shell is loaded and changed to the default before exit when closing Windows Terminal.

This fix unfortunately requires a tmux session running in the background

This is another version of /dup #633, fixed with #2066, in PR #2928.
