Subject problem for restore FB2.1 backup in FB2.5
Author Maziar
My default charset is UNICODE_FSS
It can restore in FB2.1 BUT when try restore in FB2.5 i get this error in restore :

gbak:restoring domain RDB$39
IBE: Invalid token.
Malformed string.

The RDB$FIX_METADATA seems don't help me
1.with "NONE" parameter every time do result with some record any time and commit
2.with "UNICODE_FSS" parameter raise error malformed string at line86 col:17
But no any help in restore this database with this parameter

any help is welcome :-)
