使用IronPython中的编解码器读取UTF-8文件

Question

我有一个以UTF-8编码的.csv文件,它包含拉丁语和西里尔语符号.

;F1;F2;abcdefg3;F200
;ABSOLUTE;NOMINAL;NOMINAL;NOMINAL
o1;1;USA;???????????;1223

我正在尝试在IronPython 2.7.1中执行以下脚本:

import codecs

f = codecs.open(r"file.csv", "rb", "utf-8")
f.next()

在执行f.next()期间,会发生异常:

Traceback (most recent call last):
  File "c:\Program Files\Microsoft Visual Studio 10.0\Common7\IDE\Extensions\Microsoft\Python Tools for Visual Studio\1.1\visualstudio_py_repl.py", line 492, in run_file_as_main
    code.Execute(self.exec_mod)
  File "<string>", line 4, in <module>
  File "C:\Program Files\IronPython 2.7.1\Lib\codecs.py", line 684, in next
    return self.reader.next()
  File "C:\Program Files\IronPython 2.7.1\Lib\codecs.py", line 615, in next
    line = self.readline()
  File "C:\Program Files\IronPython 2.7.1\Lib\codecs.py", line 530, in readline
    data = self.read(readsize, firstline=True)
  File "C:\Program Files\IronPython 2.7.1\Lib\codecs.py", line 477, in read
    newchars, decodedbytes = self.decode(data, self.errors)
UnicodeEncodeError: ('unknown', '\x00', 0, 1, '')

同时在CPython 2.7中,脚本可以正常工作.同样在IronPython 2.7.1下面的脚本工作正常:

import codecs

f = codecs.open(r"file.csv", "rb", "utf-8")
f.readlines()

有谁知道什么可能导致这种奇怪的行为？

看起来这可能是处理编解码器的方式中的错误next()。您能用要重现的附件打开一个问题吗？
