  352. .
  353. This manual page lists the standard
  354. .B groff
  355. glyph names and the default input mapping, \%latin-1.
  356. .
  357. The glyphs in this document will look different depending
  358. on which output device was chosen (with option
  359. .B \-T
  360. for the
  361. .BR man (1)
  362. program or the roff formatter).
  363. .
  364. Glyphs not available for the device that
  365. is being used to print or view this manual page will be marked with
  366. .ie \n(.g `(N/A)'; the device currently used is `\*(.T'.
  367. .el `(N/A)'.
  368. .
  369. .
  370. .P
  371. In the actual version,
  372. .B groff
  373. provides only \%8-bit characters for direct input and named entities
  374. for further glyphs.
  375. .
  376. On ASCII platforms, input character codes in the range 0 to 127 (decimal)
  377. represent the usual \%7-bit ASCII characters, while codes between 127
  378. and 255 are interpreted as the corresponding characters in the
  379. .I \%Latin-1
  380. .RI ( \%ISO-8859-1 )
  381. code set by default.
  382. .
  383. This mapping is contained in the file \f(CWlatin1.tmac\fP
  384. and can be changed by loading a different input encoding.
  385. .
  386. Note that some of the input characters are reserved by
  387. .BR groff ,
  388. either for internal use or for special input purposes.
  389. .
  390. On EBCDIC platforms, only code page
  391. .B cp1047
  392. is supported (which contains the same characters as \%Latin-1; the
  393. input encoding file is called \f(CWcp1047.tmac\fP).
  394. .
  395. Again, some input characters are reserved for internal and special purposes.
  396. .
  397. It is rather straightforward (for the experienced user) to set up other
  398. \%8-bit encodings like
  399. .IR \%Latin-2 ;
  400. since
  401. .B groff
  402. will use Unicode in the next major version, no additional encodings
  403. are provided.
  404. .
  405. .
  406. .P
  407. All roff systems provide the concept of named glyphs.
  408. .
  409. In traditional roff systems, only names of length\ 2 were used, while
  410. groff also provides support for longer names.
  411. .
  412. It is strongly suggested that only named glyphs are used for all
  413. character representations outside of the printable \%7-bit ASCII range.
  414. .
  415. .
  416. .P
  417. Some of the predefined groff escape sequences (with names of length\ 1)
  418. also produce single characters; these exist for historical reasons or
  419. are printable versions of syntactical characters.
  420. .
  421. They include `\f(CW\e\e\fP', `\f(CW\e\'\fP', `\f(CW\e`\fP', `\f(CW\e-\fP',
  422. `\f(CW\e.\fP', and `\f(CW\ee\fP'; see
  423. .BR groff (@MAN7EXT@).
  424. .
  425. .
  426. .P
  427. In groff, all of these different types of characters and glyphs can be
  428. tested positively with the `\f(CW.if\ c\fP' conditional.

  435. In this section, the glyphs in groff are specified in tabular
  436. form.
  437. .
  438. The meaning of the columns is as follows.
  439. .
  440. .
  441. .TP
  442. .I "Output"
  443. shows how the glyph is printed for the current device; although
  444. this can have quite a different shape on other devices, it always
  445. represents the same glyph.
  446. .
  447. .
  448. .TP
  449. .I "Input name"
  450. specifies how the glyph is input either directly by a key on the
  451. keyboard, or by a groff escape sequence.
  452. .
  453. .
  454. .TP
  455. .I "Input code"
  456. applies to glyphs which can be input with a single character, and
  457. gives the ISO \%Latin-1 decimal code of that input character.
  458. .
  459. Note that this code is equivalent to the lowest 256 Unicode characters,
  460. including \%7-bit ASCII in the range 0 to\ 127.
  461. .
  462. .
  463. .TP
  464. .I "PostScript name"
  465. gives the usual PostScript name of the glyph.
  466. .
  467. .
  468. .TP
  469. .I "Unicode decomposed"
  470. is the glyph name used in composite glyph names.

  478. These are the basic glyphs having 7-bit ASCII code values assigned.
  479. .
  480. They are identical to the printable characters of the
  481. character standards \%ISO-8859-1 (\%Latin-1) and Unicode (range
  482. .IR "C0 Controls and Basic Latin" ).
  483. .
  484. The glyph names used in composite glyph names are `u0020' up to `u007E'.
  485. .
  486. .
  487. .P
  488. Note that input characters in the range \%0\-31 and character 127 are
  489. .I not
  490. printable characters.
  491. .
  492. Most of them are invalid input characters for
  493. .B groff
  494. anyway, and the valid ones have special meaning.
  495. .
  496. For EBCDIC, the printable characters are in the range \%66\-255.

  740. Glyph names can be embedded into the document text by using escape
  741. sequences.
  742. .
  743. .BR groff (@MAN7EXT@)
  744. describes how these escape sequences look.
  745. .
  746. Glyph names can consist of quite arbitrary characters from the
  747. ASCII or \%Latin-1 code set, not only alphanumeric characters.
  748. .
  749. Here some examples:
  750. .
  751. .TP
  752. \f(CW\e\fP\fIc\fP
  753. A glyph having the name
  754. .IR c ,
  755. which consists of a single character (length\ 1).
  756. .
  757. .TP
  758. \f(CW\e(\fP\fIch\fP
  759. A glyph having the 2-character name
  760. .IR ch .
  761. .
  762. .TP
  763. \f(CW\e[\fP\fIchar_name\fP\f(CW]\fP
  764. A glyph having the name
  765. .I char_name
  766. (having length 1, 2, 3, .\|.\|.).
  767. .
  768. .TP
  769. \f(CW\e[\fP\fIbase_glyph composite_1 composite_2 .\|.\|.\fP\f(CW]\fP
  770. A composite glyph; see below for a more detailed description.
  771. .
  772. .
  773. .P
  774. In groff, each \%8-bit input character can also referred to by the construct
  775. `\f(CW\e[char\fP\fIn\fP\f(CW]\fP' where
  776. .I n
  777. is the decimal code of the character, a number between 0 and\ 255
  778. without leading zeros (those entities are
  779. .I not
  780. glyph names).
  781. .
  782. They are normally mapped onto glyphs using the \f(CW.trin\fP request.
  783. .
  784. Another special convention is the handling of glyphs with names directly
  785. derived from a Unicode code point; this is discussed below.
  786. .
  787. Moreover, new glyph names can be created by the \f(CW.char\fP request; see
  788. .BR groff (@MAN7EXT@).
  789. .
  790. .P
  791. In the following, a plus sign in the `Notes' column indicates that this
  792. particular glyph name appears in the PS version of the original troff

  958. The extensible bracket pieces are font-invariant glyphs.
  959. .
  960. In classical troff only one glyph was available to vertically extend
  961. brackets, braces, and parentheses: `bv'.
  962. .
  963. We map it rather arbitrarily to u23AA.
  964. .
  965. .P
  966. Note that not all devices contain extensible bracket pieces which can
  967. be piled up with `\f(CW\eb\fP' due to the restrictions of the escape's
  968. piling algorithm.

  1008. Another complication is the fact that some glyphs which represent bracket
  1009. pieces in original troff can be used for other mathematical symbols also,
  1010. for example `lf' and `rf' which provide the `floor' operator.
  1011. .
  1012. Other devices (most notably for DVI output) don't unify such glyphs.
  1013. .
  1014. For this reason, the four glyphs `lf', `rf', `lc', and `rc' are not
  1015. unified with similarly looking bracket pieces.
  1016. .
  1017. In
  1018. .BR groff ,
  1019. only glyphs with long names are guaranteed to pile up correctly for all
  1020. devices (provided those glyphs exist).

  1260. These glyphs are intended for technical use, not for real Greek; normally,
  1261. the uppercase letters have upright shape, and the lowercase ones are
  1262. slanted.
  1263. .
  1264. There is a problem with the mapping of letter phi to Unicode.
  1265. .
  1266. Prior to Unicode version\ 3.0, the difference between U+03C6, GREEK
  1267. SMALL LETTER PHI, and U+03D5, GREEK PHI SYMBOL, was not clearly described;
  1268. only the glyph shapes in the Unicode book could be used as a reference.
  1269. .
  1270. Starting with Unicode\ 3.0, the reference glyphs have been exchanged and
  1271. described verbally also: In mathematical context, U+03D5 is the stroked
  1272. variant and U+03C5 the curly glyph.
  1273. .
  1274. Unfortunately, most font vendors didn't update their fonts to
  1275. this (incompatible) change in Unicode.
  1276. .
  1277. At the time of this writing (February 2003), it is not clear yet whether
  1278. the Adobe Glyph Names `phi' and `phi1' also change its meaning if used for
  1279. mathematics, thus compatibility problems are likely to happen \(en being
  1280. conservative, groff currently assumes that `phi' in a PostScript symbol
  1281. font is the stroked version.
  1282. .P
  1283. In groff, symbol `\f(CW\e[*f]\fP' always denotes the stroked version of
  1284. phi, and `\f(CW\e[+f]\fP' the curly variant.
