Display UTF-8 characters in sakura, slitaz5.rc2

Hi

I have problem to display UTF-8 chars in sakura terminal, while in xterm they're displayed correctly. The problem is that in the xterm I could not compose characters such as(u+2663).

How can I display & compose UTF-8 characters in the sakura terminal?

Slitaz 5.rc2

Thank you for help

I can't reproduce your problem. (u+2663) is displayed without any glitch on my system. How did you create the filename in your example?

1. open leafpad

2. write symbol u+2663

3. on save choose UTF-8 otherwise wont save it

4. observe problem

it works the same way if I just try to write compose character in sakura terminal

1. open sakura terminal

2. write symbol u+2663

(the symbol u+2663 is displayed as '?')

I tried out on newly installed GNU/slitaz 5.rc without any additional configuration (the problem appear).

BUT

Now I found out that the problem is not appearing while the system is not installed. ( is going from Live CD..)

Thank you very much for response

I was able to reproduce problem on an updated full install with these locale settings.

root@slitaz:/home/tux# locale

LANG=C

LC_CTYPE="C"

LC_NUMERIC="C"

LC_TIME="C"

LC_COLLATE="C"

LC_MONETARY="C"

LC_MESSAGES="C"

LC_PAPER="C"

LC_NAME="C"

LC_ADDRESS="C"

LC_TELEPHONE="C"

LC_MEASUREMENT="C"

LC_IDENTIFICATION="C"

LC_ALL=C

5.0-rc2 displays a ? instead of non-ascii characters with locale set to posix on full or frugal install.

The solution is to set the locale to valid country_region.

Using terminal as root:

Launch ncurses dialog → [c]tazlocale[/c]

Launch yad gui → [c]tazbox locale[/c]

or

Applications/Preferences/System language

Reboot to reload console keymap.

Re: Display UTF-8 characters in sakura, slitaz5.rc2

Thinking out loud...

So, according to Alphanumeric article from Wikipedia:

In the POSIX/C[2] locale, there are either 36 (A-Z0-9, case insensitive) or 62 (A-Za-z0-9, case-sensitive) alphanumeric characters.

SliTaz uses UTF-8-based locales by default.

C locale is not equal en_US (en_US.UTF-8 if to be precise) because C locale using only ASCII character set, and not using other symbols, like €, or £, or ♣.

So, if we want to use any symbol without restriction, we wanted to switch to UTF-8 (read: switch to any SliTaz locale isatead of C).

As for topic starter's question about "composition":

meydlo,

File /usr/share/X11/locale/en_US.UTF-8/Compose contains huge number of composition rules.

Many locales (in fact, not only en_US.UTF-8) used this file to compose symbols on user input (it does not matter—in console, in text editor, or in web browser).

All you need—is define Compose key (by default it absent on modern keyboards, so you need to re-define other one). Personally me prefere to use RightAlt key as Compose key. Here two ways to define it:

1. Edit/create (as root) file /etc/X11/xorg.conf.d/40-Keyboard.conf, here is my file:

Section "InputClass"

    Identifier "Keyboard Defaults"

    MatchIsKeyboard "yes"

    Option "XkbLayout" "us,ru"

    Option "XkbOptions" "grp:ctrl_shift_toggle, grp_led:scroll, compose:ralt, terminate:ctrl_alt_bksp"

EndSection

Reboot system to use new settings.

2. Use setxkbmap

setxkbmap -layout "us,ru" -option "grp:ctrl_shift_toggle,compose:ralt"

No need to reboot, changes are applied immediately. This line can be placed to the end of ~/.profile to execute it automatically on system logon.

Ok, now we have Compose key. How to use it?

Rules, described in /usr/share/X11/locale/en_US.UTF-8/Compose is not difficult to human reading (Multi_key is our Compose key):

Press (and release) Compose key, press (and release) "o" key and "c" key—you'll get Copyright sign ©

Main rule—compose symbol from simple symbols—looks like © is composed from letters "o" and "c"; "±" is composed from "+" and "-";

"¢" = "c" + "|";

"£" = "L" + "-";

"€" = "C" + "=" (or "=" + "C", or "c" + "=", or "E" + "="...)

Unicode U26×× symbols described too:

♩♪♫♬♭♮♯☭Ⓐ♥☺☹

Sad, but there is no rule to compose ♣ (but you can add your own compose rules).

I suggest you to use Character Map application: install gucharmap package.
