Font that was once rendering correctly, now shows empty boxes

[burhan]

I am on Windows 10 Pro 1803 (17134.228) on a Dell XPS 15 9570 with the 4K screen (not sure if this matters).

I have been using "Ubuntu mono derivative Powerline" without issues on WSL. Yesterday I noticed that my zsh prompt no longer renders the font correctly; it now shows empty boxes instead of >>> (three arrows).

Here is what it used to look like:

I'm really not sure what triggered this; here is my Windows Update log:

Hey @burhan - in the erroneous case, what font is your Console using?

[burhan]

The same font, I haven't changed the console settings.

Are you sure that the font is still installed?

It's possible that the Ubuntu app got updated - I don't believe that should change the console settings, but it might have. Can you post a screenshot of the font dialog?

None of those updates should have anything to do with conhost, so there must be something else at work here.

@Burhan: And do you have a link to the font you're using? Is it this one?

[burhan]

The font is installed as per the properties window.

The font installed is the same one as in your link @bitcrazed

I am not sure if this is related, but in VS code, the font renders correctly

In cmd.exe properties, the font shows and its used by default correctly:

Could you share your zsh configuration declaring the color chevrons?

i.e. echo $PROMPT

[burhan]

${SSH_TTY:+"%F{9}%n%f%F{7}@%f%F{3}%m%f "}%F{4}${_prompt_sorin_pwd}%(!. %B%F{1}#%f%b.)${editor_info[keymap]}

And what does your .~/zshrc look like?

And any other steps you took to configure your prompt to use that theme would be useful. Difficult to diagnose unless we can repro.

I am using Prezto, and the .zshrc is pretty stock:

burhan@xps:~$ cat ~/.zshrc
#
# Executes commands at the start of an interactive session.
#
# Authors:
#   Sorin Ionescu <sorin.ionescu@gmail.com>
#

# Source Prezto.
if [[ -s "${ZDOTDIR:-$HOME}/.zprezto/init.zsh" ]]; then
  source "${ZDOTDIR:-$HOME}/.zprezto/init.zsh"
fi

# Customize to your needs...

# enable color support of ls and also add handy aliases
if [ -x /usr/bin/dircolors ]; then
    test -r ~/.dircolors && eval "$(dircolors -b ~/.dircolors)" || eval "$(dircolors -b)"
    alias ls='ls --color=auto'
    alias dir='dir --color=auto'
    #alias vdir='vdir --color=auto'

    alias grep='grep --color=auto'
    alias fgrep='fgrep --color=auto'
    alias egrep='egrep --color=auto'
fi
export PYENV_ROOT="$HOME/.pyenv"
export PATH="$PYENV_ROOT/bin:$PATH"
eval "$(pyenv init -)"
export PATH="$HOME/.rbenv/bin:$PATH"
eval "$(rbenv init -)"
export PATH="$HOME/.rbenv/plugins/ruby-build/bin:$PATH"

Here is the Prezto configuration (the customized parts, removed the commented parts for brevity):

Deja Vu seems not cover these angle brackets and Console need to support font fallback to display them. Therefore, Get rid of GDI ASAP please!

@burhan, The fonts in provided VS Code and cmd.exe screenshots look different to the naked eye. While the one in cmd.exe definitely looks like Ubuntu Mono, the VS Code one most certainly doesn't.

[qidydl]

I wonder if this is the same problem as #3257? There's a lot more discussion there and a potential workaround, selecting "Install for all users" on the font may get it working properly.

[zadjii-msft]

Hey so this was filed like, four years ago, and obviously there's been a lot of work done since then. Is this still happening? I think we added some better support for unsupported glyphs in the console in the latest Win11 bits. Then there's also the Terminal, which may have never had this issue at all. We never did nail down a specific repro for this one, so maybe it's gone/?
