 Posted: Tue Nov 21, 2017 12:12 pm Post subject: My console cannot display unicode character |
 |
|
To show utf-8 characters in consoles, I followed the gentoo UTF-8 wiki: https://wiki.gentoo.org/wiki/UTF-8
But when i use vim in normal mode, and type :digraphs, only characters under 256 is shown correctly, characters bigger than 256 is shown as a question mark.
UTF-8 works well in a Xwindow terminal, but not in console(command line interface), so it should not be the reason of vim.
Besides, if i insert unicode characters in a text file, such test.txt, and use cat command to display the text file, unicode characters is displayed as question marks in console.
In my /etc/rc.conf, I have
In /etc/conf.d/consolefont:
| Code: |
consolefont="lat9w-16"
|
Here is the result of locale command
| Code: |
[root@icefire etc]#locale
LANG=en_US.utf8
LC_CTYPE="en_US.utf8"
LC_NUMERIC="en_US.utf8"
LC_TIME="en_US.utf8"
LC_COLLATE="en_US.utf8"
LC_MONETARY="en_US.utf8"
LC_MESSAGES="en_US.utf8"
LC_PAPER="en_US.utf8"
LC_NAME="en_US.utf8"
LC_ADDRESS="en_US.utf8"
LC_TELEPHONE="en_US.utf8"
LC_MEASUREMENT="en_US.utf8"
LC_IDENTIFICATION="en_US.utf8"
LC_ALL=
|
utf8 is alse enabled in kernel config file
| Code: |
[root@icefire linux-4.12.12-gentoo]#grep -i utf8 /usr/src/linux-4.12.12-gentoo/.config
CONFIG_FAT_DEFAULT_IOCHARSET="utf8"
# CONFIG_FAT_DEFAULT_UTF8 is not set
CONFIG_NLS_DEFAULT="utf8"
CONFIG_NLS_UTF8=y
|
and my /etc/env.d/02locale :
| Code: |
[root@icefire etc]#cat /etc/env.d/02locale
# Configuration file for eselect
# This file has been automatically generated.
LANG="en_US.utf8"
|
and locale is set as this:
| Code: |
[root@icefire etc]#eselect locale list
Available targets for the LANG variable:
[1] C
[2] en_US.utf8 *
[3] POSIX
[4] zh_CN.utf8
[ ] (free form)
|
unicode is enabled globally in /etc/portage/make.conf:
| Code: |
USE="-* -bindist -cups -kde -gnome -minimal -systemd X unicode perl python php apache2 dbus alsa pulseaudio ppp cairo encode jpeg opengl lopengl ock session startup-notification udev mmx sse sse2 vaapi vdpau xinerama xv icu readline"
|
But my console just cannot display unicode characters correctly, what's the reason? Could anyone help me?
Many thanks. |

Just a few pro-forma questions:- Have you rebuilt the recommended libraries after enabling the unicode USE flag?
- Have you confirmed that the unicode USE flag properly set by looking for it in your "emerge --info"?
- Is there a specific reason that you're disabling all of the profile specific USE flags?
It's been a while but that Wiki article worked for me.

Yes, I rebuild the world after enabling the unicode USE flag
| Code: |
emerge -auDN @world
|
And the result of emerge --info
| Code: |
[root@icefire etc]#emerge --info

As for the third point, do you mean the -* in my global USE flag in /etc/portage/make.conf ? I think i just want to disable all the flags and enable what i really need to have more control of my system.
I did this by following the installation wiki https://wiki.gentoo.org/wiki/Handbook:AMD64/Full/Installation, it says :
When USE is defined in /etc/portage/make.conf it is added (or removed if the USE flag starts with the - sign) from that default list. Users who want to ignore any default USE settings and manage it completely themselves should start the USE definition in make.conf with -*:

I have tried the default, the result is even worse, even part of characters whose code is under 255 cannot be displayed when i typed :digraphs in vim normal mode.
I have tried
consolefont="default8x16"
consolefont="lat9w-16"
consolefont="lat0-12"
consolefont="latarcyrheb-sun32"
consolefont="lat9u-16"
All of them cannot work well. |

I'm afraid your USE flags don't make sense:
| Quote: | | USE="-* -bindist -cups -kde -gnome -minimal -systemd ... |
is pointless and
| Quote: | | USE="-* ... perl python php apache2 ... |
seems strange...
You should use "-*" only if you really want a minimal system and if you know exactly what you are doing. And even then I wouldn't simply write "-*" to make.conf. I would start with a working system and remove use flag after use flag and test after each step.
I have one server which defines (only) the USE flags below in make.conf:
| Quote: | | USE="-* bzip2 gpm logrotate ncurses netifrc openrc pam pie readline udev unicode xattr zlib" |
It works and unicode works as well. But it took me weeks to get to this minimal set of use flags. Furthermore, I have about 20 lines in package.use, where I define additional use flags for some packages. |
