Korean(5) File Formats Manual Korean(5) NAME Korean, korean - Introduction to Korean language support DESCRIPTION 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 na- tional standard was KS C 5601. Under its old name, the standard was is- sued in 1982, 1987, and 1992. The operating system currently supports the KS X 1001 standard as is- sued 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. Codesets 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 of the Unicode standard, this preprocessing 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 UCS-2, UCS-4, ucs4, and UTF-8 represent these encoding formats in the names of lo- cales or codeset converters. See Unicode(5) for more informa- tion. The string cp949 represents this encoding format in the names of codeset converters. See code_page(5) for more informa- tion. The string ISO-2022-KR represents this encoding format in the names of codeset converters. These are special-purpose con- verters 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. Korean Locales The following list specifies Korean locales for Korea and the codesets they support: ko_KR.deckorean, for DEC Korean ko_KR.eucKR, for Korean EUC 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. 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. In a windows environment, you also need to set the session language. The way you do this depends on which windows environment you are using: In the Common Desktop environment (CDE), use the Language menu accessed from the login window Options button. In the DECwindows environment, use the Language Option dialog box invoked from the Session Manager's Options menu. Keyboards, Input Servers, and Input Methods The operating system supports the VT382-K Korean terminal. The operating system supports the following Korean keyboards: LK201-K LK401-K However, you can also use any standard English keyboard to enter Ko- rean. See the keyboard(5) reference page for information on loading keyboard mapping tables (keymaps) for keyboards. For the Motif environment, the operating system provides the dxhangulim input server to support Korean input methods. You can start this input server with the following command: % /usr/bin/X11/dxhangulim & The input server must be running before you start the application win- dow where you enter Korean characters. 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: Using a VT382-K terminal: Compose selects Hangul Shift+Compose selects Hanja Ctrl+Compose selects Row-Column Using an LK201* keyboard: Compose+Space selects Hangul Shift+Compose selects Hanja Ctrl+Compose+Space selects Row-Column F6 selects Phrase Using an LK401* keyboard: Compose selects Hangul Shift+Compose selects Hanja Ctrl+Compose selects Row-Column F6 selects Phrase Using any PC-style key- board: Alt+Space selects Hangul Shift+Alt+Space selects Hanja Ctrl+Alt+Space selects Row-Column F6 selects Phrase You can customize these key sequences by using the Customization menu of the dxhangulim application. Running Motif Applications X or Motif applications require non-ASCII fonts to display Korean char- acters. Therefore, you must set the font path appropriately before starting an application that displays Korean characters. An application can find Korean fonts in either of the following directories: /usr/i18n/lib/X11/fonts/decwin/75dpi, for low resolution display /usr/i18n/lib/X11/fonts/decwin/100dpi, for high resolution display Before you start a Korean application, 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 After ensuring that the font path is set correctly and that the dx- hangulim input server is running (see the section on input devices, servers, and methods), you can use the following steps to start a Ko- rean application in the DECwindows environment: If you have not already made the desired language setting, then: Choose Language from the Op- tion menu. Select the Korean language that you want the application to use. The available Korean language options reflect the different codesets supported by Korean locales, as follows: This language option is equivalent to Korean (EUC). Press the OK button. Choose the application you want to start from the Application menu. Printers 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 page printer. 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) and wwpsof(8) reference pages. Fonts that support characters defined by the DEC Korean codeset are listed in the deckorean(5) reference page. EXAMPLES This section shows the steps in the DECwindows Motif environment to set up Korean language support and start the DECterm application where you can display and input Korean text. Make sure that the font path in- cludes either the 75dpi or 100dpi directory that contains fonts for Asian languages: % xset q If neither /usr/i18n/lib/decwin/75dpi/ nor /usr/i18n/lib/decwin/75dpi/ is included in the display, add one of them to the font path. For example: % xset +fp /usr/i18n/lib/decwin/75dpi/ % xset fp rehash If it is not al- ready running, start the dxhangulim input server: % /usr/bin/X11/dxhangulim & Choose Keyboard from the Option menu In the the Keyboard Options dialog box, select the option for Korean. Then click on the Apply and OK buttons. Choose Language from the Option menu, select one of the Korean language optons in the Language Options dialog box, and click on the OK button Create a new DECterm window by choosing DECterm from the Appli- cation menu.
