I am trying to load in an old CACHE.DAT database into Intersystems Cache (2012.1.1 win32 evaluation). I’ve managed to create a namespace and database, and I’m able to query some of the database tables.

However, for other tables, I get the following error:

ERROR #5540: SQLCODE -400 Message: Unexpected error occurred: <WIDE CHAR>

The documentation tells me that this means that a multibyte character is read where a one byte character is expected. I suspect this might mean that the original database was in UTF-16, while my new installation is using UTF-8.

My question is: is there a way to either convert the database, to configure Cache so that it can deal with , or to deal with this problem in another way?

    maybe the original database was created in unicode installation
    and current installation 8-bit

    Caché read a multibyte character where a 1-byte character was expected.
