How to setup fonts in Linux subsystem?
TLDR; You need to install windows host and configure Powerline fonts bash gui properties.
found info here
you actually need to install these fonts in Windows and set the console host font to one of them.
Next open bash and click the icon in the upper left corner and select Properties. Change to the Font tab and select one of the patched fonts you just installed. They will all say "for Powerline" so just pick one of those.
How I solved this:
- Install "Sauce Code Pro Nerd Font" https://www.nerdfonts.com/font-downloads Unpack -> Open "whatever font you like".ttf and install. Check the installed font in a directory "C:\Windows\Fonts".
2.1) Open "Powershell", "Ubuntu" (or another WSL-distro), then right-click -> Properties -> Font -> Change font to "Sauce Code Pro Nerd Font".
2.2) If you use Windows Terminal. Open it -> "Ctrl+," -> find an attribute "profiles{...} -> defaults{...} -> add to "defaults" an attribute "fontFace": "SauceCodePro Nerd Font" to apply the font to all profiles or choose a profile from "list" and type the same to apply only to the given profile (e.x. "Cascadia Code PL" for Powershell, "SauseCode Pro Nerd Font" for Ubuntu).

Optional. Open VSCode -> Ctrl+, -> fontFamily: type "SauseCodePro Nerd Font" before other fonts.

You can do this with other fonts, but they need to support a powerline glyphs, e.g. "Mononoki" font.
