Python except for UnicodeError?

问题

In my code I keep getting this error...

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

I tried to put an except for UnicodeError and UnicodeEncodeError but nothing works, the problem is it's the users input so I can't control what they put so I need all encode errors to display a print that says error instead of crashing the program...

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 = ""

Traceback:

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]

回答1:

Give this a try:

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

or take a look at this post's question.

回答2:

Your print is failing. Your Windows console doesn't support printing UTF-8, you need to change the codepage:

chcp 65001

This is a Windows command, not a python command. You may need to switch fonts too, Lucida Sans Console is a Unicode font that can handle a lot more glyphs.

try this one to replace str(): source = source.encode('UTF-8')
