SUMMARY
This article lists Double-Byte Character Set (DBCS) Enabled/Localized FoxPro versions for the East Asian Region.



MORE INFORMATION
DBCS-enabled means the version of FoxPro is capable of handling double-byte characters. Localized means the version of FoxPro is a DBCS version and it displays localized languages on menus, controls, error messages, and Help files.

The Double-Byte Character Set (DBCS) is a character encoding mechanism that accommodates ideographic characters used in East Asian languages.

Characters in DBCS can be addressed using a 16-bit notation using two bytes, or double-byte, unlike Single-Byte Character Sets (SBCS), which can only represent at most 256 characters in one byte. With 16-bit notation, you can represent 65,536 (2^16) characters.

DBCS code pages contain both single and double-byte characters. The DBCS single-byte characters conform to the 8-bit national standards for each country and correspond closely to the American Standard Code for Information Interchange (ASCII) character set.

In a double-byte character set, certain ranges of code-points are designated as leading bytes. A leading byte, together with the following byte, represents a single character. This second byte is called the trailing byte or trail-byte. Each DBCS has a different set of lead-byte ranges and trail-byte ranges. Unlike leading bytes, trail-bytes in some DBCS' can overlap with the 7-bit ASCII character set.

For example, the Shift Japan Industry Standard (JIS) character set has a trail-byte range of 0x40H-0xFEH. That means a byte holding the value of 0x7DH can represent the second half of a Kanji character, not necessarily a close brace character(}).
