* @brief The encapsulation of logic for codeset negotiation
*
* The Codeset Manager is owned by the ORB_Core, initialized through Resource
* Factory configuration options. The codeset manager participates in profile
* creation by servers and connection establishment by clients. The involvement
* is necessary to supply a codeset component to the profile including for both
* chars and wide chars the native code set and any conversion code sets for
* which translators are available. The codeset manager is also responsible for
* determining the transmission codesets based an the local and remote codeset
* information. The transmission codesets are communicated via a service
* context attached to the first request sent on the new connection.
