A Mapchar set is used to map language-specific characters to other formats (for example, ü to ue). The underlying code (ASCII, UNICODE) of the characters that need to be replaced and the Mapchar set must match.
· When the database instance is configured, a conversion of these country-specific letters is implicitly allowed and stored under the Mapchar set name DEFAULTMAP (defined as ASCII).
· The DEFAULTMAP Mapchar set can be changed. Additional MapChar sets can also be defined.
· If a Mapchar set is defined as UNICODE, then it can be used for UNICODE values only.
· A Mapchar set that is not defined as UNICODE cannot be used for UNICODE values.
Mapchar sets are only of significance for internal system functions. For example, Mapchar sets are used by the MAPCHAR(x,n,i) SQL function to sort fields containing umlauts.
