mdbFontEncoding - Font Encoding
The m17n library loads information about the encoding of each font form
the m17n database by the tags <font, encoding>. The data is loaded as a
plist of this format.
FONT-ENCODING ::= PER-FONT *
PER-FONT ::= ’(’ FONT-SPEC ENCODING [ REPERTORY ] ’)’
’(’ [ FOUNDRY FAMILY
[ WEIGHT [ STYLE [ STRETCH [ ADSTYLE ]]]]] REGISTRY ’)’
ENCODING ::= SYMBOL
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.
For instance, this FONT-SPEC:
(nil alice0 lao iso8859-1)
should be applied to all fonts whose family name is ’alice0 lao’, and
registry is ’iso8859-1’.
ENCODING is a symbol representing a charset. A font matching FONT-SPEC
supports all characters of the charset, and a character code is mapped
to the corresponding glyph code of the font by this charset.
REPERTORY is a symbol representing a charset or ’nil’. Omitting it is
the same as specifying ENCODING as REPERTORY. If it is not ’nil’, the
charset specifies the repertory of the font, i.e, which character it
supports. Otherwise, whether a specific character is supported by the
font or not is asked to each font driver.
For so called Unicode fonts (registry is ’iso10646-1’), it is
recommended to specify ’nil’ as REPERTORY because such fonts usually
supports only a subset of Unicode characters.
