Computers with older operating systems with the default language set to English or other Western or Cyrillic language settings will require some setup and proper fonts (See also: List of CJK fonts) to be able to display the characters.
Newer computer operating systems may not require any additional steps to view most CJKV characters.
If you see boxes, question marks, or meaningless letters mixing into the first part, you do not have full support for East Asian characters.
Windows XP and Server 2003 include native support for East Asian languages. To install the files, check the Install files for East Asian languages in the Control Panel > Regional and Language Options > Languages. Note that a minimum of 230 MB of disk space is required and that the Windows CD-ROM is needed while installing support for East Asian languages using this method. (Non-East Asian localizations only)
Alternatively, you can download the following installation packages. No disc is needed for this option.
In the standard installation of Windows 10, Dengxian, SimFang, SimHei, SimKai, DFKai, MingLiU, Meiryo, MS Mincho, Ms Gothic, Yu Mincho, Batang, Gungsuh, Dotum and Gulim are no longer included. So when running certain apps on Windows 10, some characters display as a square or rectangular box, or as a box with a dot, question mark or "x" inside. To solve this problem, you must install the optional font feature of the specific language.
All recent versions of OS X (10.4+) support East Asian characters natively.You may need to install appropriate fonts.
GNOME supports East Asian characters natively. You may need to install appropriate fonts.
KDE 5 supports East Asian characters natively. You may need to install appropriate fonts.
KDE supports East Asian characters natively. You may need to install the following packages:
If this does not help, or works partially, but some characters are still missing, you may need to run qtconfig, and add a comprehensive unicode font to your chosen browser font's substitutions.
In order to display Chinese, Japanese and/or Korean characters, you must install some font packages:
|Chinese (both Simplified & Traditional)||fonts-arphic-ukai||fonts-arphic-uming|
There are some alternative packages for some languages, but the ones listed above do work.
To install all the fonts listed above in Debian, Ubuntu, and other variants:
sudo apt-get install fonts-arphic-ukai fonts-arphic-uming fonts-ipafont-mincho fonts-ipafont-gothic fonts-unfonts-core
For a large collection of fonts which comprehensively support Simplified Chinese, Traditional Chinese, Japanese, and Korean, with a consistent design and look, install the following package:
pacman -S adobe-source-han-sans-otc-fonts
Install the appropriate packages:
fonts-korean. The command to download and install these fonts is
yum install fonts-japanese fonts-chinese fonts-korean
Enabling the cjk (Chinese, Japanese, Korean) USE flag improves East Asian support in some packages, but is not essential.
e.g. for viewing Chinese text:
# emerge arphicfonts
Install the appropriate fonts packages. For example:
# urpmi fonts-ttf-japanese fonts-ttf-chinese fonts-ttf-korean
CJK fonts can be installed on FreeBSD using freebsd ports collection:
# cd /usr/ports/x11-fonts/cyberbit-ttfonts && make install clean # cd /usr/ports/japanese/font-kochi && make install clean
or by installing precompiled packages:
# pkg install ja-font-kochi
On NetBSD and other systems using pkgsrc, one can install CJK fonts with the following commands:
# cd /usr/pkgsrc/fonts/kochi-ttf && make install clean # cd /usr/pkgsrc/fonts/cyberbit-ttf && make install clean
Download the appropriate .ttf file (for example, kochi-gothic-subst.ttf) and copy it to your system's TrueType font directory (for example, /usr/lib/X11/fonts/TTF/). For example, (for Dejavu fonts):
wget http://downloads.sourceforge.net/project/dejavu/dejavu/2.35/dejavu-fonts-ttf-2.35.tar.bz2 tar -xjvf dejavu-fonts-ttf-2.33.tar.bz2 cp ./dejavu-fonts-ttf-2.33/ttf/* /usr/lib/X11/fonts/TTF
(or get the link to the current version here, and then update this help)
Then run (as root):
Restart X if it is in use, and the new font should be installed.
