in my python interpreter it does nothing. I'm using Terminal.app on Mac OS X and when I'm simply in in bash I have no trouble:
在我的python解释器中，它什么都不做。我使用终端。在Mac OS X上的应用程序，当我简单地在bash中，我没有麻烦:

But in the interpreter:

^^ I get nothing, it just ignores that I just pasted the character. If I use the escape \xNN\xNN representation of the middle dot '\xc2\xb7', and try to convert to unicode, trying to show the dot causes the interpreter to throw an error:
^ ^我得到什么,只是忽略我刚才贴这个角色。如果我使用的是中间点'\xc2\xb7'的escape \xNN\xNN表示，并尝试转换成unicode，试图显示点使解释器抛出一个错误:
>>> unicode('\xc2\xb7')
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
UnicodeDecodeError: 'ascii' codec can't decode byte 0xc2 in position 0: ordinal not in range(128)
I have setup 'utf-8' as my default encoding in sitecustomize.py so:
我在sitecustomize中设置了“utf-8”作为默认编码。py:
>>> sys.getdefaultencoding()
'utf-8'
What gives? It's not the Terminal. It's not Python, what am I doing wrong?!
到底发生了什么事?这不是终点站。不是Python，我做错了什么?!
This question is not related to this question, as that indivdiual is able to paste unicode into his Terminal.
这个问题与这个问题无关，因为indivdiual能够将unicode粘贴到他的终端。

unicode('\xc2\xb7') means to decode the byte string in question with the default codec, which is ascii -- and that of course fails (trying to set a different default encoding has never worked well, and in particular doesn't apply to "pasted literals" -- that would require a different setting anyway). You could use instead u'\xc2\xb7', and see:
unicode(“\xc2\xb7”)是指用默认的编解码器(即ascii)对字节字符串进行解码，而这当然失败了(尝试设置不同的默认编码从来没有成功过，尤其是不适用于“粘贴的文字”——无论如何都需要不同的设置)。你可以用u'\xc2\xb7'，看看:
>>> print(u'\xc2\xb7')

since those are two unicode characters of course. While:
因为这是两个unicode字符。而:
>>> print(u'\uc2b7')
슷
gives you a single unicode character (of some oriental persuasion -- sorry, I'm ignorant about these things). BTW, neither of these is the "middle dot" you were looking for. Maybe you mean
给你一个单一的unicode字符(一些东方的说服——对不起，我对这些东西一无所知)。顺便说一下，这两个都不是你要找的“中间点”。也许你的意思
>>> print('\xc2\xb7'.decode('utf8'))

which is the middle dot. BTW, for me (python 2.6.4 from python.org on a Mac Terminal.app):
就是中间的点。顺便说一下，对我来说(python.org上的python 2.6.4在Mac终端上):
>>> print('슷')
슷
which kind of surprised me (I expected an error...!-).
哪一种让我吃惊(我预料会有错误……)。
