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
       symbols 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.
