Character Sets Supported by Hangeul (Korean) Windows Versions

MORE INFORMATION

Two different Hangeul character standards exist in Korea. One is Wansung, and the other is Johap. The Korean government issued a Korean standard code set (KSC5601-1987), which is Wansung code set. Hangeul Windows version 3.1 supports this character set only.

Later, the Korean government amended and added to the standard and issued a new one (KSC5601-1992), which contains both Wansung and Johap code sets.

Hangeul Windows version 3.1 and Hangeul Windows 95 will not support the KSC5601-1992 standard. Instead, Hangeul Windows 95 will support the XWansung (Microsoft Extended Wansung) standard, which is an extended version of the KSC5601-1987 standard.

The XWansung Code system contains some Johab characters (not all the Johap codes). Johab characters were added into the vacant Range of old Wansung Code of Hangeul Windows version 3.1. Here are the details on the XWansung code set:
