Extract from SAP Help: "Prior to Basis Release 6.10, the code pages were listed in tables that contain the code page number, SAP characterID, and code point for each character.  As of Basis Release 6.10, characters are no longer based on SAP characterIDs but on standard Unicode scalar values. In addition, code pages contains a list of segments, and a code page building rule.

 

UNICODE CHARACTER ID

Unicode is an international standard that assigns characters from virtually every language and script a unique number, for example /B/ is U+0042 and /š/ is U+0161. The "U+" is a naming convention and the number is in hexadecimal notation. As of Basis Release 6.10 all characters are defined with a Unicode CharID, regardless of the system code page. For more information about the Unicode Standard, see the Unicode homepage: www.unicode.org

 

Note: The code pages formats in 4.6D and earlier releases and the code page format in 6.10 and later releases are incompatible, and code pages cannot be transported between releases using SAP character IDs and releasing using Unicode character IDs. It is possible to convert existing -- SAP character ID based -- code pages to Unicode-based code pages.”
