Language Support (MapChar Sets)
A MapChar set is a character set that maps language-specific characters to the ASCII code or EBCDIC code. This character set is only of any significance for internal system functions.
MapChar sets were introduced to allow letters to be converted. MapChar sets enable country-specific letters to be mapped to one or two non-country-specific letters (for example, representation of "ü" as "ue").
When the database instance is configured, a conversion of these country-specific letters is implicitly allowed and stored under the name DEFAULTMAP. The DEFAULTMAP conversion definition can be changed.
Further MapChar sets can also be defined with the Database Manager.
For example, the MapChar set is used by the MAPCHAR SQL function to sort fields containing umlauts.
With the Database Manager, you can create, display, change, or delete MapChar sets (Database Manager GUI: SAP DB 7.3 ® Creating a New Database Instance ®
