Background documentation Language Support (Mapchar Sets) Locate the document in its SAP Library structure

A Mapchar set depicts language-specific characters in an alternative manner, for example, ü becomes ue. The basic character set (ASCII, UNICODE) must match for the characters that need to be converted and the Mapchar set.

When you configure the database instance, country-specific letters can be converted implicitly and saved under the Mapchar set name DEFAULTMAP (defined as ASCII). The Mapchar set DEFAULTMAP can be changed and other Mapchar sets can also be defined.

If a Mapchar set has been defined for UNICODE, this Mapchar set can only be used for UNICODE values. If a Mapchar set has not been defined for UNICODE, it cannot be used for UNICODE values.

Mapchar sets are only of importance for internal system functions. Mapchar sets are used, for example, by the SQL function MAPCHAR (x,n,i), when sorting fields that contain umlauts.
