Bold and italic text not being displayed as expected

[videbar]

As the title says, the bold and italic text is wezterm is not being displayed as expected:

• Text that is supposed to be bold is displayed as regular text. Here is an example of the output of ls:
  On wezterm:
  
  On the ubuntu terminal:
  
• Italic text is tilted more than expected, here is an example:
  On wezterm
  
  On the ubuntu terminal:
  

I'm not submitting an issue since I'm pretty sure that the bold-text issue is due to some miss-configuration on my part and that the italic-text one is due to the text being "italized" twice, as described in #3555.

Here is mi configuration:

local wezterm = require "wezterm";
return {
    enable_tab_bar = false,
    font = wezterm.font("Fira Code Retina"),
    font_size = 13.0,
    color_scheme = "nord"
}

And here is the output of wezterm ls-fonts:

You're telling wezterm to use only the Fira Code Retina font weight, rather than use the whole font family, so none of the other font weights are matched and used.

Fix it like this:

 font = wezterm.font('Fira Code')

[videbar]

Thanks! That does indeed solve the issue of the bold text. The italics are still too tilted though. Am I right in that it may be a bug related to #3555?

[wez]

Yeah, that sounds like #3555
