NAME¶
mdbFontEncoding - Font Encoding
DESCRIPTION¶
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 ] ')'
FONT-SPEC ::=
'(' [ 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.
