Subject: [PATCH] This patch allows to add spare font besides default. Some
|
||||||
|
glyphs can be not present in default font. For this glyphs st uses
|
||||||
|
font-config and try to find them in font cache first. This patch append fonts
|
||||||
|
defined in font2 variable to the beginning of font cache. So they will be
|
||||||
|
used first for glyphs that absent in default font.
