I have a Word add-in I wrote using .NET. The add-in basically processes a Word document which is configured for MailMerge and extracts the data from the data source. I need to know which encoding Word uses to access that data source. When I use a datasource (CSV for example) that is not encoded with my default system locale, Word alerts and opens a window that enables me to choose the datasource's encoding. I can't figure out if and how Word exposes the chosen encoding.
