问题描述
我在此行上遇到编码错误：
I get encoding error on this line:
s = "%s:%s: %s: %s\n" % (filename, lineno, category.__name__, message)
UnicodeEncodeError：'ascii'无法在位置44中编码字符u'\xc4'：序号不在范围（128）
UnicodeEncodeError: 'ascii' codec can't encode character u'\xc4' in position 44: ordinal not in range(128)
我尝试通过将所有参数组合传递给字符串格式，但最接近的是ascii解码错误（通过同时传递unicode和高ascii字符串，强制将字符串转换为unicode，使用ascii解码器。
I tried to reproduce this error by passing all combinations of parameters to string format, but closest I got was "ascii decode" error (by passing unicode and high ascii string simultaneously, which forced conversion of string to unicode, using ascii decoder.
但是，我没有设法得到ascii encode错误，任何人都有想法？
However, I did not manage to get "ascii encode" error. Anybody has an idea?
推荐答案
强制参数：
s = u"\u00fc"
print str(s)
UnicodeEncodeError: 'ascii' codec can't encode character u'\xfc' in position 0: ordinal not in range(128)
这是因为您的一个参数是一个对象（不是任何类型的字符串），Python调用 str（）。有两种解决方案：对于格式（ s = u％s ...）使用unicode字符串，或者使用 repr ）。
This happens because one of your arguments is an object (not a string of any kind) and Python calls str() on it. There are two solutions: Use a unicode string for the format (s = u"%s...") or wrap each argument with repr().
