Start here:

The CSV file, being stored on disk, cannot contain Unicode strings; it
can only contain bytes. If you know the encoding (eg UTF-8, UCS-2,
etc), then you can decode it using that. If you don't, your best bet
is to ask the origin of the file; failing that, check the first few
bytes - if it's "\xFF\xFE" or "\xFE\xFF" or "\xEF\xBB\xBF", then it's
probably UTF-16LE, UTF-16BE, or UTF-8, respectively (those being the
encodings of the BOM). There may be other clues, too, but normally
it's best to get the encoding separately from the data rather than try
to decode it from the data itself.
