How are codepoints composed on a Korean keyboard?
Asian characters number in the thousands, so a special input method program is needed. From one to five keystrokes are required to compose one Korean character on the English keyboard, or you can use a Korean keyboard which contains additional compose keys and has a different layout. Most Korean dumb terminals have their own input method program stored in ROM. Solaris (dtterm) can convert ASCII character input to Korean characters. For more information on Korean input methods, see Section 4.3 of Asian-Language Support in the Solaris Operating Environment.
