70 A fontset is a collection of font related information to give
71 similar appearance (style, etc) of characters. A fontset has two
72 roles. One is to use for the frame parameter `font' as if it is an
73 ASCII font. In that case, Emacs uses the font specified for
74 `ascii' script for the frame's default font.
76 Another role, the more important one, is to provide information
77 about which font to use for each non-ASCII character.
79 There are two kinds of fontsets; base and realized. A base fontset
80 is created by `new-fontset' from Emacs Lisp explicitly. A realized
81 fontset is created implicitly when a face is realized for ASCII
82 characters. A face is also realized for non-ASCII characters based
83 on an ASCII face. All of non-ASCII faces based on the same ASCII
84 face share the same realized fontset.
86 A fontset object is implemented by a char-table whose default value
87 and parent are always nil.
89 An element of a base fontset is a vector of FONT-DEFs which itself
90 is a vector [ FONT-SPEC ENCODING REPERTORY ].
92 An element of a realized fontset is nil, t, 0, or a vector of this
95 [ CHARSET-ORDERED-LIST-TICK PREFERRED-RFONT-DEF
96 RFONT-DEF0 RFONT-DEF1 ... ]
98 RFONT-DEFn (i.e. Realized FONT-DEF) has this form:
100 [ FACE-ID FONT-DEF FONT-OBJECT SORTING-SCORE ]
102 RFONT-DEFn are automatically reordered by the current charset
105 The value nil means that we have not yet generated the above vector
106 from the base of the fontset.
108 The value t means that no font is available for the corresponding
111 The value 0 means that no font is available for the corresponding
112 range of characters in this fontset, but may be available in the
116 A fontset has 9 extra slots.
118 The 1st slot: the ID number of the fontset
121 base: the name of the fontset
126 realized: the base fontset
130 realized: the frame that the fontset belongs to
133 base: the font name for ASCII characters
138 realized: the ID number of a face to use for characters that
139 has no font in a realized fontset.
143 realized: Alist of font index vs the corresponding repertory
148 realized: If the base is not the default fontset, a fontset
149 realized from the default fontset, else nil.
152 base: Same as element value (but for fallback fonts).
155 All fontsets are recorded in the vector Vfontset_table.
160 There's a special base fontset named `default fontset' which
161 defines the default font specifications. When a base fontset
162 doesn't specify a font for a specific character, the corresponding
163 value in the default fontset is used.
165 The parent of a realized fontset created for such a face that has
166 no fontset is the default fontset.
169 These structures are hidden from the other codes than this file.
170 The other codes handle fontsets only by their ID numbers. They
171 usually use the variable name `fontset' for IDs. But, in this
172 file, we always use varialbe name `id' for IDs, and name `fontset'
173 for an actual fontset object, i.e., char-table.

1425 Modify fontset NAME to use FONT-SPEC for TARGET characters.
1427 NAME is a fontset name string, nil for the fontset of FRAME, or t for
1428 the default fontset.
1430 TARGET may be a cons; (FROM . TO), where FROM and TO are characters.
1431 In that case, use FONT-SPEC for all characters in the range FROM and
1434 TARGET may be a script name symbol. In that case, use FONT-SPEC for
1435 all characters that belong to the script.
1437 TARGET may be a charset. In that case, use FONT-SPEC for all
1438 characters in the charset.
1440 TARGET may be nil. In that case, use FONT-SPEC for any characters for
1441 that no FONT-SPEC is specified.
1443 FONT-SPEC may one of these:
1444 * A font-spec object made by the function `font-spec' (which see).
1445 * A cons (FAMILY . REGISTRY), where FAMILY is a font family name and
1446 REGISTRY is a font registry name. FAMILY may contain foundry
1447 name, and REGISTRY may contain encoding name.
1448 * A font name string.
1449 * nil, which explicitly specifies that there's no font for TARGET.
1451 Optional 4th argument FRAME is a frame or nil for the selected frame
1452 that is concerned in the case that NAME is nil.
1454 Optional 5th argument ADD, if non-nil, specifies how to add FONT-SPEC
1455 to the font specifications for TARGET previously set. If it is
1456 `prepend', FONT-SPEC is prepended. If it is `append', FONT-SPEC is
1457 appended. By default, FONT-SPEC overrides the previous settings. */)
