我有一个以 UTF-8 编码的 .csv 文件,其中包含拉丁文和西里尔文符号。
;F1;F2;abcdefg3;F200
;ABSOLUTE;NOMINAL;NOMINAL;NOMINAL
o1;1;USA;Новосибирск;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 f.next() 执行期间发生异常:
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 以下脚本工作正常:
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?
