More feedback :-)

How are you dealing with character encoding? I uploaded a CSV file that has an utf-8 character in the name of a column, and in your import flow, under "File Columns", the column name appeared incorrectly encoded (i.e. it's been latin-1'ized)

My file is most probably missing the UTF-8 BOM. I'm not sure what a good option is here.

Have an advanced setting for Sheets (on your site) and pre-set the uploaded files' encoding?

We have a preset of utf-8 and will probably have to find a way for managing encoding.
