There are different processes to upgrade to UNICODE. One for Systems which have MDMP and one for System which are not using MDMP.
The upgrade path for systems with MDMP is much more complicated than the upgrade path for non MDMP systems.
I found one transaction: smlt
There I can see that we have installed for example hungary and english.
Is this installation using MDMP?
If yes, can I deinstall this languages?
you can check NLS and specially MDMP with reports RSCP0018 and RSCPINST, or have look at table TCPDB. If you fin mor than 1 entry in TCPDB your system is MDMP.
You can not deinstall a language, but you could omit a language for upgrade.
(if you do not need it any more?)
