mdbFontset(5)			The m17n Library		   mdbFontset(5)

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
	  [ OTF-SPEC ] [ LANG-SPEC ] ')'

     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 sym-
     bols corresponding to #Mfoundry to  #Mregistry  property  of  a  font.  See
     m17nFont for the meaning of each property.

     OTF-SPEC  is  a symbol specifyng the required OTF features. The symbol name
     has the following syntax.

       OTF-SPEC-NAME ::= ':otf=' SCRIPT LANGSYS ? GSUB-FEATURES ? GPOS-FEATURES ?

       SCRIPT ::= SYMBOL
       LANGSYS ::= '/' SYMBOL

       GSUB-FEATURES ::= '=' FEATURE-LIST ?

       GPOS-FEATURES ::= '+' FEATURE-LIST ?

       FEATURE-LIST ::= '~' ? FEATURE ( ',' '~' ? FEATURE ',' ).fi

     Here, FEATURE is a four-letter Open Type feature.

     LANG-SPEC is a symbol specifying the required language support. The symbol name has the following syntax.

       LANG-SPEC-NAME ::= ':lang=' LANG

     Here, LANG is a two or three-letter ISO-639 language code.

     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.
