xt font makes UTF-8 unreadable in prompt

[fabiodl]

Problem Description

UTF-8 appears as squares

Steps to Reproduce

Configuration File

If the font is specified as
font="--dejavu sans mono-medium-r-normal---80-----iso10646-1",
then anything is ok, but the new default ( XPC { font = "xft:monospace-12")
or even font="xft:Dejavu San Mono" does not display UTF-8 chars

Checklist

• [ y] I've read CONTRIBUTING.md

• I tested my configuration

  • [y] With xmonad commit 33a86c0
  • [y] With xmonad-contrib commit 20fdcbad0181d9e8fc7571799b1bb02952489df6

font="xft:Dejavu San Mono"

Is this a typo? I would expect a UTF-8 capable font is being able to display UTF-8 characters, regardless of how it's specified.

Are you talking about xmobar instead of xmonad?

xmobar does not have xft enabled by default, so you need to install it as follows.

stack install xmobar --flag xmobar:with_xft

The title mentions the prompt; while this should probably be an issue in the contrib repo, it does sound like an xmonad issue

no, about prompts. Go to window: Bring window: etc.
For instance it is sufficient to open this page in a browser https://ja.wikipedia.org/wiki/%E6%97%A5%E6%9C%AC%E8%AA%9E so that the title has utf-8 and do a bring window.

I tried capital letters in different places and different fonts. While the font visibly changed, the problem remained

I don't think it's a typo, I was able to reproduce the as well (the exact font is in my config, I'd link to it later today)

So I was looking into this a bit yesterday and it's definitely not just an issue with printing. At least the font that we open via xftFontOpen can't display the respective unicode characters (i.e., xftCharExists returns False on the respective glyphs). It feels unintuitive that we somehow open a wrong font and no-one has noticed this in all of these years
