58 A fontset is a collection of font related information to give
59 similar appearance (style, etc) of characters. A fontset has two
60 roles. One is to use for the frame parameter `font' as if it is an
61 ASCII font. In that case, Emacs uses the font specified for
62 `ascii' script for the frame's default font.
64 Another role, the more important one, is to provide information
65 about which font to use for each non-ASCII character.
67 There are two kinds of fontsets; base and realized. A base fontset
68 is created by `new-fontset' from Emacs Lisp explicitly. A realized
69 fontset is created implicitly when a face is realized for ASCII
70 characters. A face is also realized for non-ASCII characters based
71 on an ASCII face. All of non-ASCII faces based on the same ASCII
72 face share the same realized fontset.
74 A fontset object is implemented by a char-table whose default value
75 and parent are always nil.
77 An element of a base fontset is a vector of FONT-DEFs which itself
78 is a vector [ FONT-SPEC ENCODING REPERTORY ].
80 An element of a realized fontset is nil, t, 0, or a vector of this
83 [ CHARSET-ORDERED-LIST-TICK PREFERRED-RFONT-DEF
84 RFONT-DEF0 RFONT-DEF1 ... ]
86 RFONT-DEFn (i.e. Realized FONT-DEF) has this form:
88 [ FACE-ID FONT-DEF FONT-OBJECT SORTING-SCORE ]
90 RFONT-DEFn are automatically reordered by the current charset
93 The value nil means that we have not yet generated the above vector
94 from the base of the fontset.
96 The value t means that no font is available for the corresponding
99 The value 0 means that no font is available for the corresponding
100 range of characters in this fontset, but may be available in the
104 A fontset has 9 extra slots.
106 The 1st slot: the ID number of the fontset
109 base: the name of the fontset
114 realized: the base fontset
118 realized: the frame that the fontset belongs to
121 base: the font name for ASCII characters
126 realized: the ID number of a face to use for characters that
127 has no font in a realized fontset.
131 realized: Alist of font index vs the corresponding repertory
136 realized: If the base is not the default fontset, a fontset
137 realized from the default fontset, else nil.
140 base: Same as element value (but for fallback fonts).
143 All fontsets are recorded in the vector Vfontset_table.
148 There's a special base fontset named `default fontset' which
149 defines the default font specifications. When a base fontset
150 doesn't specify a font for a specific character, the corresponding
151 value in the default fontset is used.
153 The parent of a realized fontset created for such a face that has
154 no fontset is the default fontset.
157 These structures are hidden from the other codes than this file.
158 The other codes handle fontsets only by their ID numbers. They
159 usually use the variable name `fontset' for IDs. But, in this
160 file, we always use variable name `id' for IDs, and name `fontset'
161 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. */)
