71 .\"
72 .
73 This manual page lists the standard
74 .B @T_ROFF@
75 glyph names and the default input mapping, \%latin1.
76 .
77 The glyphs in this document look different depending
78 on which output device was chosen (with option
79 .B \-T
80 for the
81 .BR man (1)
82 program or the roff formatter).
83 .
84 Glyphs not available for the device that is being used to print or
85 view this manual page are marked with
86 .ie \n(.g \[oq](N/A)\[cq]; the device currently used is \[oq]\*(.T\[cq].
87 .el \[oq](N/A)\[cq].
88 .
89 .
90 .P
91 In the actual version,
92 .B @T_ROFF@
93 provides only \%8-bit characters for direct input and named entities
94 for further glyphs.
95 .
96 On ASCII platforms, input character codes in the range 0 to 127
97 (decimal) represent the usual \%7-bit ASCII characters, while codes
98 between 127 and 255 are interpreted as the corresponding characters in
99 the
100 .I \%latin1
101 .RI ( \%ISO-8859-1 )
102 code set by default.
103 .
104 This mapping is contained in the file \f(CWlatin1.tmac\fP
105 and can be changed by loading a different input encoding.
106 .
107 Note that some of the input characters are reserved by
108 .BR @T_ROFF@ ,
109 either for internal use or for special input purposes.
110 .
111 On EBCDIC platforms, only code page
112 .I cp1047
113 is supported (which contains the same characters as \%latin1; the
114 input encoding file is called \f(CWcp1047.tmac\fP).
115 .
116 Again, some input characters are reserved for internal and special purposes.
117 .
118 .
119 .P
120 All roff systems provide the concept of named glyphs.
121 .
122 In traditional roff systems, only names of length\ 2 were used, while
123 @T_ROFF@ also provides support for longer names.
124 .
125 It is strongly suggested that only named glyphs are used for all
126 character representations outside of the printable \%7-bit ASCII range.
127 .
128 .
129 .P
130 Some of the predefined @T_ROFF@ escape sequences (with names of length\ 1)
131 also produce single glyphs; these exist for historical reasons or
132 are printable versions of syntactical characters.
133 .
134 They include \[oq]\f(CW\e\e\fP\[cq], \[oq]\f(CW\e\'\fP\[cq],
135 \[oq]\f(CW\e`\fP\[cq], \[oq]\f(CW\e-\fP\[cq], \[oq]\f(CW\e.\fP\[cq],
136 and \[oq]\f(CW\ee\fP\[cq]; see
137 .BR @L_ROFF@ (@MAN7EXT@).
138 .
139 .
140 .P
141 In @T_ROFF@, all of these different types of characters and glyphs can be
142 tested positively with the \[oq]\f(CW.if\ c\fP\[cq] conditional.
143 .

148 .
149 In this section, the glyphs are specified in tabular form.
150 .
151 The meaning of the columns is as follows.
152 .
153 .
154 .TP
155 .I "Output"
156 shows how the glyph is printed for the current device; although
157 this can have quite a different shape on other devices, it always
158 represents the same glyph.
159 .
160 .
161 .TP
162 .I "Input name"
163 specifies how the glyph is input either directly by a key on the
164 keyboard, or by a roff escape sequence.
165 .
166 .
167 .TP
168 .I "Input code"
169 applies to glyphs which can be input with a single character, and
170 gives the ISO \%latin1 decimal code of that input character.
171 .
172 Note that this code is equivalent to the lowest 256 Unicode characters,
173 including \%7-bit ASCII in the range 0 to\ 127.
174 .
175 .
176 .TP
177 .I "PostScript name"
178 gives the usual PostScript name of the glyph.
179 .
180 .
181 .TP
182 .I "Unicode decomposed"
183 is the glyph name used in composite glyph names.
184 .
185 The names in the Unicode column look like
186 .B u0021
187 or
188 .BR u0041_0300 .
189 .
190 In @T_ROFF@, the corresponding Unicode characters can be constructed
191 by adding a backslash and a pair of square brackets, for example
192 .B \e[u0021]
193 or
194 .BR \e[u0041_0300] .
195 .
196 .
197 .\"
198 .SS "7-bit Character Codes 32-126"
199 .\"
200 .
201 These are the basic glyphs having 7-bit ASCII code values assigned.
202 .
203 They are identical to the printable characters of the
204 character standards \%ISO-8859-1 (\%latin1) and Unicode (range
205 .IR "Basic Latin" ).
206 .
207 The glyph names used in composite glyph names are \[oq]u0020\[cq] up
208 to \[oq]u007E\[cq].
209 .
210 .
211 .P
212 Note that input characters in the range \%0\-31 and character 127 are
213 .I not
214 printable characters.
215 .
216 Most of them are invalid input characters for
217 .B @T_ROFF@
218 anyway, and the valid ones have special meaning.
219 .
220 For EBCDIC, the printable characters are in the range \%66\-255.

239 Most of the remaining characters not in the just described ranges print as
240 themselves; the only exceptions are the following characters:
241 .
242 .
243 .TP
244 .B \`
245 the ISO \%latin1 \[oq]Grave Accent\[cq] (code\ 96) prints as \[oq], a
246 left single quotation mark; the original character can be obtained
247 with \[oq]\f(CW\e`\fP\[cq].
248 .
249 .
250 .TP
251 .B \*(aq
252 the ISO \%latin1 \[oq]Apostrophe\[cq] (code\ 39) prints as ', a right
253 single quotation mark; the original character can be obtained with
254 \[oq]\f(CW\e(aq\fP\[cq].
255 .
256 .
257 .TP
258 .B -
259 the ISO \%latin1 \[oq]Hyphen, Minus Sign\[cq] (code\ 45) prints as a
260 hyphen; a minus sign can be obtained with \[oq]\f(CW\e-\fP\[cq].
261 .

264 .B ~
265 the ISO \%latin1 \[oq]Tilde\[cq] (code\ 126) is reduced in size to be
266 usable as a diacritic; a larger glyph can be obtained with

467 .SS "Named Glyphs"
468 .\"
469 .
470 Glyph names can be embedded into the document text by using escape
471 sequences.
472 .
473 .BR @L_ROFF@ (@MAN7EXT@)
474 describes how these escape sequences look.
475 .
476 Glyph names can consist of quite arbitrary characters from the
477 ASCII or \%latin1 code set, not only alphanumeric characters.
478 .
479 Here some examples:
480 .
481 .TP
482 \f(CW\e(\fP\fIch\fP
483 A glyph having the 2-character name
484 .IR ch .
485 .
486 .TP
487 \f(CW\e[\fP\,\fIchar_name\/\fP\f(CW]\fP
488 A glyph having the name
489 .I char_name
490 (having length 1, 2, 3, \&.\|.\|.).
491 .
492 Note that \[oq]\fIc\fP\[cq] is not the same as
493 \[oq]\f(CW\e[\fP\,\fIc\/\fP\f(CW]\fP\[cq] (\,\fIc\fP\ a single
494 character): The latter is internally mapped to glyph name
495 \[oq]\e\fIc\fP\[cq].
496 .
497 By default, @T_ROFF@ defines a single glyph name starting with a
498 backslash, namely \%\[oq]\e-\[cq], which can be either accessed as
499 \[oq]\f(CW\e\-\fP\[cq] or \[oq]\f(CW\e[-]\fP\[cq].
500 .
501 .TP
502 \f(CW\e[\fP\,\fIbase_glyph composite_1 composite_2 \&.\|.\|.\/\fP\f(CW]\fP
503 A composite glyph; see below for a more detailed description.
504 .
505 .
506 .P
507 In @T_ROFF@, each \%8-bit input character can also referred to by the construct
508 \[oq]\f(CW\e[char\fP\,\fIn\/\fP\f(CW]\fP\[cq] where
509 .I n
510 is the decimal code of the character, a number between 0 and\ 255
511 without leading zeros (those entities are
512 .I not
513 glyph names).
514 .
515 They are normally mapped onto glyphs using the \f(CW.trin\fP request.
516 .
517 .P
518 Another special convention is the handling of glyphs with names directly
519 derived from a Unicode code point; this is shown in the
520 \[oq]Unicode\[cq] column of the table below.
521 .
522 In general, all glyphs not having a name as listed in this manual page can
523 be accessed with the \[oq]\f(CW\e[u\fP\,\fIXXXX\/\fP\f(CW]\fP\[cq]
524 construct.
525 .
526 Moreover, new glyph names can be created by the \f(CW.char\fP request; see
527 .BR @L_ROFF@ (@MAN7EXT@).
528 .
529 .P
530 In the following, a plus sign \[oq]+\[cq] in the \[oq]Notes\[cq] column
531 indicates that this particular glyph name appears in the PS version of
532 the original troff documentation, CSTR\ 54.
533 .
534 .P
535 Entries marked with \[oq]***\[cq] denote glyphs for mathematical
536 purposes (mainly used for DVI output).
537 .
538 Normally, such glyphs have metrics which make them unusable in normal
539 text.

737 The extensible bracket pieces are font-invariant glyphs.
738 .
739 In classical troff only one glyph was available to vertically extend
740 brackets, braces, and parentheses: `bv'.
741 .
742 We map it rather arbitrarily to u23AA.
743 .
744 .P
745 Note that not all devices contain extensible bracket pieces which can
746 be piled up with \[oq]\f(CW\eb\fP\[cq] due to the restrictions of the
747 escape\[aq]s piling algorithm.

787 Another complication is the fact that some glyphs which represent
788 bracket pieces in original troff can be used for other mathematical
789 symbols also, for example \[oq]lf\[cq] and \[oq]rf\[cq] which provide
790 the \[oq]floor\[cq] operator.
791 .
792 Other devices (most notably for DVI output) don\[aq]t unify such
793 glyphs.
794 .
795 For this reason, the four glyphs \[oq]lf\[cq], \[oq]rf\[cq],
796 \[oq]lc\[cq], and \[oq]rc\[cq] are not unified with similarly looking
797 bracket pieces.
798 .
799 In
800 .BR @T_ROFF@ ,
801 only glyphs with long names are guaranteed to pile up correctly for all
802 devices (provided those glyphs exist).

1194 .I Greek glyphs
1195 .P
1196 These glyphs are intended for technical use, not for real Greek; normally,
1197 the uppercase letters have upright shape, and the lowercase ones are
1198 slanted.
1199 .
1200 There is a problem with the mapping of letter phi to Unicode.
1201 .
1202 Prior to Unicode version\ 3.0, the difference between U+03C6, GREEK
1203 SMALL LETTER PHI, and U+03D5, GREEK PHI SYMBOL, was not clearly described;
1204 only the glyph shapes in the Unicode book could be used as a reference.
1205 .
1206 Starting with Unicode\ 3.0, the reference glyphs have been exchanged and
1207 described verbally also: In mathematical context, U+03D5 is the stroked
1208 variant and U+03C6 the curly glyph.
1209 .
1210 Unfortunately, most font vendors didn\[aq]t update their fonts to
1211 this (incompatible) change in Unicode.
1212 .
1213 At the time of this writing (January 2006), it is not clear yet
1214 whether the Adobe Glyph Names \[oq]phi\[cq] and \[oq]phi1\[cq] also
1215 change its meaning if used for mathematics, thus compatibility
1216 problems are likely to happen \[en] being conservative, @T_ROFF@
1217 currently assumes that \[oq]phi\[cq] in a PostScript symbol font is
1218 the stroked version.
1219 .P
1220 In @T_ROFF@, symbol \[oq]\f(CW\e[*f]\fP\[cq] always denotes the stroked
1221 version of phi, and \[oq]\f(CW\e[+f]\fP\[cq] the curly variant.
