pyExcelerator和utf8？

我的问题是，当用它来转换utf8文件（包含例如'LATIN SMALL LETTER O WITH ACUTE'（U + 00F3）“ó”）时，它会产生字节序列0x43 0x04，它由两个都打开office和ms excel为“y”（0x43，而只是丢弃0x04）。

有谁知道我或pyExcelerator做错了什么？

您应该手动编码/解码utf-8文件中的数据：

reader = csv.reader(inputFile, delimiter=sepChar)
for line in reader:
  if (lno == 0 and titlePresent):
    if (len(titleCols) == 0):
      titleCols = line
    writeExcelHeader(worksheet, titleCols)
  else:
    # writeExcelRow(worksheet, lno, line)
    # in unicode function source file encoding should be passed
    writeExcelRow(worksheet, lno, [unicode(cell, 'utf-8') for cell in line])


def writeExcelRow(worksheet, lno, columns):
  """ Write a non-header row into the worksheet """
  cno = 0
  for column in columns:
    #worksheet.write(lno, cno, column)
    worksheet.write(lno, cno, column.encode('utf-8'))
    cno = cno + 1
