rxvt-unicode is a well known terminal emulator for the X window system with support for Unicode. It also supports multiple fonts. This is great because not all fonts have great looking glyphs for all character blocks.
Here is my
.Xdefaults config for rxvt-unicode’s fonts settings:
URxvt.font: xft:inconsolata:size=12,\ -*-unifont-*-*-*-*-*-*-*-*-*-*-*-*
I learned about Inconsolata in a post titled Top 10 Programming Fonts (Hivelogic, 2009). It is a free, very readable fixed width font that I use in my terminal emulator and my website’s
GNU Unifont is a bitmap font that covers the entire Unicode’s Basic Multilingual Plane (code points
0xFFFF). It’s the perfect fallback font because even though it is ugly, otherwise unsupported glyphs are never rendered as a question mark, or worse, as blank space.
The only downside I find is that rxvt-unicode uglyfully scales the second font to fit the first font’s character cells.
Now here is a stitched screenshot of my terminal’s rendering of UTF-8-demo.txt. See how Unifont takes over anywhere Inconsolata lacks a glyph for a code point. You can add other specialised fonts in the
.Xdefaults configuration and they will be tried in the specified order.
