CSV file encoded in UTF-8 with BOM

[jduchateau]

When using a UTF-8 CSV file starting with a BOM, the BOM is not ignored.
Which brings this funny error message: Attribute Country Code does not exist. because it undoubtedly exists in the file.

@prefix ex: <http://example.com/> .
@prefix rml: <http://w3id.org/rml/> .
