Bug 190109 – Not monospaced

• Status: RESOLVED
• Resolution: WONTFIX
• Component: CSS

[Дилян Палаузов]

I use WebKit from https://webkitgtk.org/ 2.22.2 with Epiphany 3.30.1 .  In the latter I have chosen under “Preferences” as monospace font “Monospace Regular 10”.  Visiting pages like https://tools.ietf.org/html/rfc4918 do not show text as monospace.  The problem does not seem to be with Epiphany: https://gitlab.gnome.org/GNOME/epiphany/issues/82 .  I have compiled WebKitGtk and Epiphany myself.

How can I find out, why WebKit does not render monospaced areas as such?

You almost certainly have applied some custom fontconfig contfiguratoion, which is not supportable.

[Дилян Палаузов]

I did `fontconfig/configure && make install` hence I do not have custom fontconfig configuration.

[Michael Catanzaro]

It's very hard to believe that this would be broken by default. Please post the output of:

$ fc-match monospace

I think it's almost surely going to return a non-Monospace font. You probably have some fontconfig configuration files in your home directory or something.

[Дилян Палаузов]

That was it: creating ~/.config/fontconfig/fonts.conf with suitable
  <alias>
    <family>monospace</family>
    <prefer><family>Liberation Mono</family></prefer>
  </alias>


tweaked both `fc-match monospace` and WebKit to use correct monospace font.

[Michael Catanzaro]

Well something is wrong with your fontconfig installation, since that should be configured at the system level, and not require anything in your home directory....

[Дилян Палаузов]

Perhaps.  I installed fonts manually.  fontcongig seems to declare in its default configurition files which fonts are preferred monospace.

fc-list :spacing=100 emits
  /usr/share/fonts/truetype/anonymous_pro/Anonymous_Pro.ttf: Anonymous Pro:style=Regular
  /usr/share/fonts/truetype/ubuntu-font-family-0.80/UbuntuMono-BI.ttf: Ubuntu Mono:style=Bold Italic
  /usr/share/fonts/truetype/noto-hints/NotoMono-Regular.ttf: Noto Mono:style=Regular

  /usr/share/fonts/truetype/anonymous_pro/Anonymous_Pro_I.ttf: Anonymous Pro:style=Italic
  /usr/share/fonts/truetype/ubuntu-font-family-0.80/UbuntuMono-R.ttf: Ubuntu Mono:style=Regular
  /usr/share/fonts/truetype/noto-hints/NotoColorEmoji.ttf: Noto Color Emoji:style=Regular
  /usr/share/fonts/truetype/anonymous_pro/Anonymous_Pro_B.ttf: Anonymous Pro:style=Bold

but fc-match monospace printed a totally different font.  Apparently for the output of fc-match the font properties are irrelepant and only the fc-configuration files matter, which by default do not mention the files from the list above and have to be set manually.

The conclusion it, that Epiphany lets the user set a monospaced font, but the choice gets ignored, so the case went back to https://gitlab.gnome.org/GNOME/epiphany/issues/82  .
