Linux install utf 8

How to Enable or Missing UTF-8 Support in Linux

When you access a specific web page or any text file which is written in a different language or use an ASCII message, then your system will not be able to detect language.

Because of that, you will see “X” all over the file. All this happens because of missing UTF-8, or you have selected the wrong locales.

Through this article, we will enable UTF-8 support using the terminal in Linux. Before that, first understand what is UTF-8, Why the system requires UTF-8 support?

Note:- In this article, some of the text will not appear as we intend so that you may see a square box or any other characters.

What is UTF-8?

We live in the 21st century where every information gets transfer in a second over the internet, just like reading this guide. It’s doesn’t matter whether you are in the US or Japan.

Because of vast data reachability, there is a problem of language locale inconsistency.

The actual text is “TrendOceans からのこのガイド” In case of missing UTF-8 support. You will see “X TPՎTrendOceans.”

Now you know why the problem occur and let’s solve this issue.

First of all, open a terminal and type the following command to check whether the locale package is available on your system.

# dpkg -l locales

[email protected]:~# dpkg -l locales Desired=Unknown/Install/Remove/Purge/Hold | Status=Not/Inst/Conf-files/Unpacked/halF-conf/Half-inst/trig-aWait/Trig-pend |/ Err?=(none)/Reinst-required (Status,Err: uppercase=bad) ||/ Name Version Architecture Description +++-==============-=============-============-=================================> ii locales 2.32-0ubuntu3 all GNU C Library: National Language > lines 1-6/6 (END)

If the output is not the same as above, then you need to install the local package.

# apt-get install locales

In the next step, you need to reconfigure the locale package, type the below command, and make sure to run as root.

# dpkg-reconfigure locales

Now you will see the number of locales available to generate the following UTF-8 support. Using the arrow key, navigate up and down to choose en_US-UTF-8 or any other UTF-8 locale.

Package configuration Configuring locales Locales are a framework to switch between multiple languages and allow users to use their language, country, characters, collation order, etc. Please choose which locales to generate. UTF-8 locales should be chosen by default, particularly for new installations. Other character sets may be useful for backwards compatibility with older systems and software. Locales to be generated: [ ] All locales ↑ [ ] aa_DJ ISO-8859-1 [ ] aa_DJ.UTF-8 UTF-8 [ ] aa_ER UTF-8 [ ] [email protected] UTF-8 [ ] ********** UTF-8 [*] en_US.UTF-8 UTF-8 [ ] ********** UTF-8 ↓

After that, again, it will ask you to select the default locale. On this screen, also select en_US.UTF-8.

 Default locale for the system environment: None C.UTF-8 en_US.UTF-8 ******.UTF-8

Now, wait for the Linux System to generate an automated locale according to your selected preference.

How can I enable UTF-8 support in the Linux console?

Right now, it looks like this:

it’s a real 80×25 textmode terminal, so you can’t use more than 256 characters. Use framebuffer console if you want real utf-8.

Check that you have the locales package installed

you can navigate that list with the up/down arrow keys, for example choose en_US-UTF-8

edit your .bashrc by adding the following lines:

export LC_ALL=en_US.UTF-8 export LANG=en_US.UTF-8 export LANGUAGE=en_US.UTF-8 

Run the locale command ,the output should be similar to this::

LANG=en_US.UTF-8 LANGUAGE=en_US:en LC_CTYPE="en_US.UTF-8" LC_NUMERIC="en_US.UTF-8" LC_TIME="en_US.UTF-8" LC_COLLATE="en_US.UTF-8" LC_MONETARY="en_US.UTF-8" LC_MESSAGES="en_US.UTF-8" LC_PAPER="en_US.UTF-8" LC_NAME="en_US.UTF-8" LC_ADDRESS="en_US.UTF-8" LC_TELEPHONE="en_US.UTF-8" LC_MEASUREMENT="en_US.UTF-8" LC_IDENTIFICATION="en_US.UTF-8" LC_ALL= 

I do have the package installed — I think it comes by default with Debian Wheezy. It’s just that the console wasn’t in UTF-8 mode.

Sure (it’s limited on the number of glyphs, but it seems your locale is using UTF-8 encoding).

#!/bin/sh # send character-string to enable UTF-8 mode if test ".$1" = ".off" ; then printf '\033%%@' else printf '\033%%G' fi 

and (calling it «utf8»), «utf8 on» turns the encoding on.

Using the example given with pstree , here is an example after running the script (before, the same sort of output as in the question):

As noted in a comment, there’s a script unicode_start which does more, but all that is needed to address the question posed is the small script used as an example.

Addressing a different comment: At least on my system (and in the screenshot shown in the question), all of the characters used by pstree are supplied in the 512-glyph font used by default for Unicode support in the Linux console.
