Korean, korean - Introduction to Korean language support
KS X 1001 is a Korean national standard that defines a set of graphic
characters to be used for information interchange. The operating sys‐
tem supports this standard with coded character sets, locales, device,
and other kinds of system files. The former name for the Korean
national standard was KS C 5601. Under its old name, the standard was
issued in 1982, 1987, and 1992.
The operating system currently supports the KS X 1001 standard as
issued in 1992, but does not include the Johab subset of Hangul charac‐
ters in the DEC Korean and Korean EUC codesets that are discussed in
this reference page. The standard specifies that support for the Johab
subset of Hangul characters is optional.
The operating system supports the following codesets for Korean by
means of locales, codeset converters, or both: The string deckorean
represents this codeset in the names of locales and codeset converters.
See deckorean(5) for more information.
If Korean character mapping in an input file that you want to
convert to DEC Korean conforms to Version 1.1 of the Unicode
standard, you must preprocess the data by running the UNI‐
CODE-1-1-UCS-4_UCS-4 converter before running the UCS-4_decko‐
rean converter. If the character mapping of an input file con‐
forms to Version 2.0 or later of the Unicode standard, this pre‐
processing step is not necessary.
If the output from the cp949_UTF-8 codeset converter is then
converted to DEC Korean, some Hangul characters may be lost. See
code_page(5) for more information. The string eucKR represents
this codeset in the names of locales and codeset converters. See
eucKR(5) for more information. The strings UTF-16, UCS-4, and
UTF-8 represent these encoding formats in the names of locales
or codeset converters. See Unicode(5) for more information. The
string cp949 represents this encoding format in the names of
codeset converters. See code_page(5) for more information. The
string ISO-2022-KR represents this encoding format in the names
of codeset converters. These are special-purpose converters
used only by certain mail applications.
See the i18n_intro(5) reference page for general information about
codesets. See the iconv_intro(5) reference page for a discussion of
codeset converters and how to use them.
The following list specifies Korean locales for Korea and the codesets
ko_KR.deckorean, for DEC Korean
ko_KR.eucKR, for Korean EUC
ko_KR.UTF-8, for UTF-8
The ko_KR.deckorean locale has a ko_KR.deckorean@ucs4 variant for use
by applications that need to convert DEC Korean to UCS-4 process code
in order to perform certain character-classification operations. The
UTF-8 locale also uses UCS-4 process code but expects file code to be
in UTF-8 format.
You can use the locale command (see locale(1)) to display the names of
locales installed on your system. See i18n_intro(5) for information on
setting locale from the operating system command line.
In the Common Desktop Environment (CDE), you need to set the session
language at login time. Use the Language menu that is accessed from the
Options button of the Login window.
Keyboards, Input Servers, and Input Methods
The operating system supports the VT382-K Korean terminal.
You can use any standard English PC-style keyboard to enter Korean.
See the keyboard(5) reference page for information on loading keyboard
mapping tables (keymaps) for keyboards.
For a Motif environment like CDE, the operating system provides the
dxhangulim and dxim input servers to support Korean input methods. The
dxhangulim input server is started automatically for your CDE session
when you specify Korean as your session language at login time. See
dxhangulim(1X) and dxim(1X) for more information about these input
Korean characters can be entered by the following input methods: Hangul
Hanja Row-Column Code Phrase Input Method
You select the Korean input method by using a key or key sequence as
follows: If you are using a VT382-K terminal:
Compose selects Hangul
Shift+Compose selects Hanja
Ctrl+Compose selects Row-Column
If you are using any PC-style keyboard:
Shift+Space selects Hangul
Shift+Alt+Space selects Hanja
Ctrl+Alt+Space selects Row-Column
F6 selects Phrase
If you are using the dxim input server, use F3 to invoke the
Korean input method in combination with F5 to select Hangul.
Once in Hangul, use F6 to switch to Hanja or F7 to switch to
Row-Column. Use F5 to switch back to Hangul. The F12 function
key selects Phrase input.
You can customize these key sequences by using the Customization menu
of the dxhangulim or dxim applications.
Fonts for Motif Applications
X or Motif applications require non-ASCII fonts to display Korean char‐
acters. An application can find Korean fonts in either of the follow‐
ing directories: /usr/i18n/lib/X11/fonts/decwin/75dpi, for low resolu‐
tion display /usr/i18n/lib/X11/fonts/decwin/100dpi, for high resolution
For applications running under CDE, no user commands are necessary to
make Korean fonts available if they are installed on the system or pro‐
vided through a font server. For applications running in other environ‐
ments, you may need to use the following command to check the font
path: % xset q
If one of the directories in the preceding list is not in the font
path, the following example shows how to add the directory. You can
substitute 100dp for 75dpi if you want high resolution display.
% xset +fp /usr/i18n/lib/X11/decwin/75dpi/ % xset fp rehash
The operating system supports the following Korean printers. The asso‐
ciated print filter is noted in parentheses following the printer name.
The LA380-K is a Korean graphic line printer. The DL510-KA is a Korean
For information on setting up and configuring these printers, refer to
the i18n_printing(5) and lprsetup(8) reference pages.
For information on how to use other kinds of printers to print Korean
characters, see the i18n_printing(5), pcfof(8), and wwpsof(8) reference
Fonts that support characters defined by the DEC Korean codeset are
listed in the deckorean(5) reference page.
