We are converting data from a competitor for a new client, so I don't have access to the original server, just the .bak file. Here is a screenshot of some of the columns in SQL server
As you can see from the screenshot, the column names all have the same kind of format. It is not consistent across tables -- some have all the names correct, some have only one or two incorrect. Each attempt to restore leads to this same weird obfuscation. I have no idea what next steps to take.
