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.
