My basic procedure in troubleshooting is starting from the known and 
working out to the unknown. So my questions about the schema(s) and the 
table definition where to establish a know starting point. Also a common 
issue that hit this list are multiple versions(across schemas) of an 
object in a database and code hitting the wrong version. One of the 
signs of that being error messages of the form you got.

Notepad is not a text editor to use in general and in particular for 
data transformation work. It has limited knowledge of the text format. 
If you need to do that on Windows use Wordpad or better yet Notepad++:

The original encoding was Win-10 (Japanese) correct?
