在Python 3中打印非ASCII字符 [英] Printing non-ascii characters in Python 3

问题描述

所以我想打印特殊字符，如®（保留符号字符）。看起来很容易。我找到其他人试图做同样的事情但带有版权符号并赋予它一个旋转，但它错误：

So I want to print special characters like ® (the Reserved Sign char). Seems easy enough. I found someone else trying to do the same thing but with the copyright symbol and gave it a whirl, but it errored out:

Python 3.4.3 (v3.4.3:9b73f1c3e601, Feb 24 2015, 22:43:06) [MSC v.1600 32 bit (Intel)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> print('\u00a9')
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "C:\Python34\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 '\xa9' in position 0: character maps to <undefined>

我以前在Python 3.4.2上遇到这个问题，只是更新到3.4.3，但它似乎有同样的问题。

I was previously having this issue on Python 3.4.2, and just updated it to 3.4.3, but it seems to be having the same problem.

另一个有趣的事情要注意的是，当我尝试打印这些字符时，python只有错误。如果我没有打印，请：

The other interesting thing to note is that python only errors out when I try to print these characters. If I leave them unprinted, then:

>>> a = '\xae'
>>> if a == '\xae':
...     print(True)
...
True

推荐答案

要打印这些字符，您可以使用：

To print these characters you could use:

ReservedSignChar = '®';
x = ReservedSignChar.encode('utf-8');
print(x);
