in2csv reading sheets with utf-8 names

Created by: Fil

sheet names in utf-8, containing an accent

The command in2csv --sheet=BÉBÉ file.xls raises: usr/local/lib/python2.7/site-packages/xlrd/book.py:439: UnicodeWarning: Unicode equal comparison failed to convert both arguments to Unicode - interpreting them as being unequal No sheet named <'B\xc3\x89B\xc3\x89'>

Quick fix in in2csv.py:

        if self.args.sheet:
            kwargs['sheet'] = self.args.sheet.decode('utf-8')

(I think this bug and the fix are because I'm using python2.7)

Another way of getting this sheet is by adding an argument sheetnum with:

        self.argparser.add_argument('--sheetnum', dest='sheetnum',
                                    help='The name of the Excel sheet to operate on.')
…
        if self.args.sheetnum:
            kwargs['sheet'] = int(float(self.args.sheetnum))
