[Groff] new backend for UTF-8 output |
|
Date: |
Mon, 10 Jan 2000 12:38:47 +0100 (MET) |
Hello,
Here is a patch which enables groff to produce UTF-8 encoded Unicode output,
for use on ttys like the UTF-8 enabled xterm. It introduces a new option
"-Tutf8", similar to "-Tlatin1". The behaviour of existing backends is not
changed.
Bruno
2000-01-08 Bruno Haible <address@hidden>
* devutf8/Makefile.sub, devutf8/DESC.proto, devutf8/R.proto: New files.
* Makefile.in (DEVDIRS): Add devutf8.
* grotty/tty.cc: Include device.h.
(glyph): Change type of 'code' to 'unsigned int'.
(tty_printer): New field is_utf8. Constructor takes device argument.
(tty_printer::tty_printer): If device if "utf8", set is_utf8.
(tty_printer::add_char): Change type of first arg to 'unsigned int'.
(tty_printer::put_char): New function.
(tty_printer::end_page): Use put_char instead of ::putchar.
(make_printer): Pass device to tty_printer constructor.
* nroff.sh: Determine default device by calling 'locale'. As a
fallback, look at all of $LC_ALL, $LC_CTYPE, $LANG, $LESSCHARSET.
Recognize UTF-8 locales.
* tmac/eqnrc: Recognize utf8 like latin1.
* tmac/troffrc: Device utf8 needs tmac.tty.

+ The following from groff_char.7 are unmapped:
+
+ f \(Fn florin

+ -) \(st suchthat

+ unmapped:
+
+ <= \(lh handleft
+ => \(rh handright
+ \(bs solid ball
+
+ Character 0x002D has not been given a name because its Unicode name
+ "HYPHEN-MINUS" is so ambiguous that it's unusable for serious typographic use.
+
+ The following are mentioned in the original troff manual but not in
+ groff_char.7:
+
+ \(sr square root
+ \(rn overline
+ \(is integral sign
+
+ The following, mentioned in the original troff manual, are only approximate:
+
+ \(lk middle part of big left curly brace
+ \(rk middle part of big right curly
brace
+
+ \(bv has been mapped to 0x2502, not 0x2759, because it appears to mean
+ "bar vertical", not "bold vertical".
+
+ The line
+ char173 24 0 0x00AD
+ has been removed, because tmac.tty contains the line
+ ".if c\[char173] .shc \[char173]"
+ (i.e. if char173 is defined, then tell the troff engine that it shall use
+ char173 as soft hyphen - otherwise it will use hy = HYPHEN), and char173 in
+ Markus Kuhn's UCS-fonts looks more like a minus sign than like a hyphen.
+ Once Markus Kuhn's fonts are fixed, this line should be added again, because
+ ISO-8859-x describes the soft hyphen character as "a graphic character that
+ is imaged by a graphic symbol identical with, or similar to, that representing
+ HYPHEN, for use when a line break has been established within a word" - which
+ is exactly groff's use of 'shc'.
+
+ Using unnamed characters:
+ Assume you want to use a Unicode character not provided in the list, say
+ U+20AC. You need to do two things:
+ - Add a line "--- 24 0 0x20AC" (the second column is
+ computed as 24 * wcwidth(0x20AC)) to the file R.proto, or, when groff
+ is already installed, to the four fonts files in
+ $(prefix)/share/groff/font/devutf8/.
+ - In your source file, use the notation \N'8364' where 8364 is the decimal
+ representation of 0x20AC.
