Python除UnicodeError外？

Question

在我的代码中,我不断收到此错误...

UnicodeEncodeError: 'charmap' codec can't encode character '\u2013' in position 390: character maps to <undefined>

我试图除了UnicodeError和UnicodeEncodeError之外没有任何效果,问题是它是用户输入所以我无法控制它们放置的内容所以我需要所有编码错误来显示错误而不是崩溃程序的打印. .

try:
    argslistcheck = argslist[0]
    if argslistcheck[0:7] != "http://":
        argslist[0] = "http://" + argslist[0]
    with urllib.request.urlopen(argslist[0]) as url:
        source = url.read()
        source = str(source, "utf8")
    except urllib.error.URLError:
        print("Couln't connect")
        source = ""
    except UnicodeEncodeError:
        print("There was an error encrypting...")
        source = ""

追溯:

Traceback (most recent call last):
  ..... things leading up to error
  File "C:\path", line 99, in grab print(source)
  File "C:\Python33\lib\encodings\cp437.py", line 19, in encode
    return codecs.charmap_encode(input,self.errors,encoding_map)[0]
UnicodeEncodeError: 'charmap' codec can't encode character '\u2013' in position 390: character maps to <undefined>

Answer 1

您的打印失败.您的Windows控制台不支持打印UTF-8,您需要更改代码页:

chcp 65001

这是Windows命令,而不是python命令.您可能还需要切换字体,Lucida Sans Console是一种可以处理更多字形的Unicode字体.

Answer 2

试试这个：

source = str(source, encoding='utf-8', errors = 'ignore')

或者看看这个帖子的问题。
