29 | ;; Set standard fontname specification of characters in the default |
30 | ;; fontset to find an appropriate font for each charset. This is used | |
31 | ;; to generate a font name for a fontset if the fontset doesn't | |
32 | ;; specify a font name for a specific character. The specification | |
33 | ;; has the form (FAMILY . REGISTRY). FAMILY may be nil, in which | |
34 | ;; case, the family name of default face is used. If REGISTRY | |
35 | ;; contains a character `-', the string before that is embedded in | |
36 | ;; `CHARSET_REGISTRY' field, and the string after that is embedded in | |
37 | ;; `CHARSET_ENCODING' field. If it does not contain `-', the whole | |
38 | ;; string is embedded in `CHARSET_REGISTRY' field, and a wild card | |
39 | ;; character `*' is embedded in `CHARSET_ENCODING' field. The | |
40 | ;; REGISTRY for ASCII characters are predefined as "ISO8859-1". | |
