How to use wide-range characters a.k.a. UTF-8 in NetBSD.
Just to show off. That's how UTF-8 encoded spam will look like
This is all about Unicode on NetBSD.
wscons doesn't support UTF-8, you'll need X11 and a proper X terminal emulator for this to be of any use, or you get character mash for lunch! Only the [ASCII] part of Unicode, namely the first 128 characters, will work in your wscons console, as they overlap in both UTF-8 and ISO-8859 character sets:

Unofficial patches for 3.0 release can be found here: ftp://tink.ims.ac.jp/pub/NetBSD/uwscons/
To make packages that support it use the ncurses library with wide-characters, add to /etc/mk.conf
chsh -s /bin/ksh
This one is an OpenBSD based Korn shell, works pretty well compared to the pdksh.
cd /usr/pkgsrc/shells/mksh make install clean chsh -s /usr/pkg/bin/mksh
Note: The stable version 4.2.x won't work. UTF-8 in the Z shell is enabled by default since 4.3.2.
cd /usr/pkgsrc/shells/zsh-current make install clean chsh -s /usr/pkg/bin/zsh
Works out of the box.
cd /usr/pkgsrc/shells/tcsh make install clean chsh -s /usr/pkg/bin/tcsh
Works out of the box.
cd /usr/pkgsrc/shells/bash make install clean chsh -s /usr/pkg/bin/bash
Set the variables LANG and LC_CTYPE in your shell configuration file
export LANG="en_US.UTF-8" export LC_CTYPE="en_US.UTF-8" export LC_ALL=""
or if you have a C-style shell
setenv LANG "en_US.UTF-8" setenv LC_CTYPE "en_US.UTF-8" setenv LC_ALL ""
The other locale variables should be left untouched, which is "C" by default, to not confuse programs. Other locales than en_US probably won't work too well, since the fonts aren't in the base system yet, but you can install them and try your luck, of course.
The result should look like
% locale LANG="en_US.UTF-8" LC_CTYPE="en_US.UTF-8" LC_COLLATE="C" LC_TIME="C" LC_NUMERIC="C" LC_MONETARY="C" LC_MESSAGES="en_US.UTF-8" LC_ALL=""
- Versions 239 and over work well with default "fixed" font
- Also works with ttf DejaVu Mono font
- Appears to have trouble with some other fonts such as Bitstream Vera Sans Mono despite this font being more complete than DejaVu
- Awesome and works great with the ttf Bitstream Vera Sans Mono or DejaVu Mono.
- Somewhat bloated considering the dependencies.
cd /usr/pkgsrc/x11/rxvt-unicode make install clean
- Works, as the 'u' might suggest, but last time I checked it sucked. Anyone?
- Doesn't work and probably never will.
- Doesn't work either. Last time I checked the author was too busy with real-life.
- Set the shell environment variable LESSCHARSET to "utf-8".
defutf8 on encoding UTF-8
Or change "Display character set" in the options menu.
/set recode_autodetect_utf8 yes /set recode_fallback iso-8859-1 (or whatever seems fit) /set recode_out_default_charset UTF-8 /set term_charset UTF-8 /save
/set term_type utf-8 /save
- NetBSD's vi is based on nvi. It doesn't support wide-range characters as of version 1.79nb16 from 10/23/96, which is the one in current 4.99.15 and all releases thereunder.
- pkgsrc' nvi (v1.81.5) is supposed to work with wide-range characters after some tweaks.
; === Set character encoding === (setq locale-coding-system 'utf-8) (set-terminal-coding-system 'utf-8) (set-keyboard-coding-system 'utf-8) (set-selection-coding-system 'utf-8) (prefer-coding-system 'utf-8)
This one gives you umlauts:
; === Make ä, ö, ü, ß work === (set-language-environment 'german)
mutt should work with all the above. If it doesn't, put in your .muttrc something like
If you haven't set it in PKG_DEFAULT_OPTIONS already, you may also add to mk.conf
If you have files containing non-ASCII ISO-8859 characters your system now will assume these are UTF-8 characters. They're not though, and the characters in these files will be misinterpreted which means that tools that use them will start breaking. Use iconv to convert these, which is part of the base system.
iconv -f iso8859-1 -t utf-8 file >file.new
- Be careful with special characters in filenames, as they'll look weird when you try to access them from a non-unicode environment.
