Rational® ClearQuest® version 7.0 supports mixed character-set deployments in which different machines with different local character sets connect to the same Rational ClearQuest database set. In such deployments, all Rational ClearQuest applications can read and modify the data in the database according to the characters of the Rational ClearQuest data code page. Earlier versions of Rational ClearQuest, applications could read data from the database set, but not write data to the database set, if the application's local character set did not correspond to the data code page for the database set. In version 7.0, this restriction is removed, and full read and modify operation on the data is permitted.
