Python 除了 UnicodeError？

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>

我尝试放置一个 UnicodeError 和 UnicodeEncodeError 除外，但没有任何效果，问题是它是用户输入的，所以我无法控制他们放置的内容，所以我需要所有编码错误来显示错误而不是崩溃的打印程序...

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 = ""

回溯:

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>

试一试:

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