>Hi all,
>I think I copied this encryption routine from one of the files in UT. It has been working for us fine until it was deployed to a client using the 1251 codepage. This is a code snippet to reproduce the problem. I've been using the CPCONVERT() to try to fix the problem but cannot. Is there something I can do? Creating temporary tables/cursors is a valid solution for me.
