NAME

       mdbFontset - Fontset

DESCRIPTION

       The m17n library loads a fontset definition from the m17n database by
       the tags <fontset, FONTSET-NAME>. The plist format of the data is as
       follows:

       FONTSET ::= PER-SCRIPT * PER-CHARSET * FALLBACK *

       PER-SCRIPT ::= ’(’ SCRIPT PER-LANGUAGE + ’)’

       PER-LANGUAGE ::= ’(’ LANGUAGE FONT-SPEC-ELEMENT + ’)’

       PER-CHARSET ::= ’(’ CHARSET FONT-SPEC-ELEMENT + ’)’

       FALLBACK ::= FONT-SPEC-ELEMENT

       FONT-SPEC-ELEMENT ::= ’(’ FONT-SPEC [ FLT-NAME ] ’)’

       FONT-SPEC ::=
            ’(’ [ FOUNDRY FAMILY
                  [ WEIGHT [ STYLE [ STRETCH [ ADSTYLE ]]]]]
                REGISTRY ’)’

       SCRIPT is a symbol of script name (e.g. latin, han) or nil. LANGUAGE is
       a two-letter symbol of language name code defined by ISO 639 (e.g. ja,
       zh) or nil.

       FONT-SPEC is to specify properties of a font. FOUNDRY to REGISTRY are
       symbols corresponding to #Mfoundry to #Mregistry property of a font.
       See m17nFont for the meaning of each property.

       FLT-NAME is a name of Font Layout Table (Font Layout Table).

EXAMPLE

       This is an example of PER_SCRIPT.

       (han
         (ja
           ((jisx0208.1983-0)))
         (zh
           ((gb2312.1980-0)))
         (nil
           ((big5-0))))

       It instructs the font selector to use a font of registry
       ’jisx0208.1983-0’ for a ’han’ character (i.e. a character whose
       #Mscript property is ’han’) if the character has #Mlanguage text
       property ’ja’ in an M-text and the character is in the repertories of
       such fonts. Otherwise, try a font of registry ’gb2312.1980-0’ or
       ’big5-0’. If that ’han’ character does not have #Mlanguage text
       property, try all three fonts.

       See the function mdraw_text() for the detail of how a font is selected.
