Detect some Unicode BOMs and always treat data starting with a BOM as text. We might need to fine-tune this later but it should be an improvement already. In the Edit Dialog remove the BOM from the text editor but keep it in the hex editor. Also add it back to the text when saving changes in text mode. This way the BOM is out of the way for text edits but is not lost either when editing a cell.
