-i3 uses X core fonts (not Xft) for rendering window titles. You can use
-+xfontsel(1)+ to generate such a font description. To see special characters
-(Unicode), you need to use a font which supports the ISO-10646 encoding.
+i3 has support for both X core fonts and FreeType fonts (through Pango) to

+To generate an X core font description, you can use +xfontsel(1)+. To see
+special characters (Unicode), you need to use a font which supports the
+ISO-10646 encoding.

+A FreeType font description is composed by a font family, a style, a weight,
+a variant, a stretch and a size.
+FreeType fonts support right-to-left rendering and contain often more
+Unicode glyphs than X core fonts.
 
 If i3 cannot open the configured font, it will output an error in the logfile
