Stop GTK+ display of substitute fonts in editor?
In GTK+ text editors, glyphs missing from the default font will be drawn from some other installed font that has them. How do I prevent this so that just the "missing glyph" glyph is shown?
ok, some unknown "text editor" is missing fonts on some unknown Operating system
set the default font in this editor to your system default
install the missing fonts
( see your package manager for that)
There is no easy way to do this. Most editors built with GTK+ use GtkTextView, but there is no control over glyph substitution in that module. Within GTK+, it is Pango that handles this. You can't change the behavior with a config file, but you can use the fallback attribute to make a special build that doesn't take substitute glyphs.
At a lower level, font substitution for the whole system is managed by fontconfig, but there is no way to disable that feature in fontconfig.
