UnicodeDecodeError：“ utf-8”编解码器无法解码字节0xa0

Question

我有这样的纯文本，这是APUE https://justpaste.it/68ah7的第07章

尝试打开时

In [79]: fd = open("07.org", "r+")     

In [80]: text = fd.read()              
---------------------------------------------------------------------------
UnicodeDecodeError                        Traceback (most recent call last)
<ipython-input-80-7eca0a263a1d> in <module>
----> 1 text = fd.read()

~/anaconda3/lib/python3.7/codecs.py in decode(self, input, final)
    320         # decode input (taking the buffer into account)
    321         data = self.buffer + input
--> 322         (result, consumed) = self._buffer_decode(data, self.errors, fi
nal)
    323         # keep undecoded input until the next call
    324         self.buffer = data[consumed:]

UnicodeDecodeError: 'utf-8' codec can't decode byte 0xa0 in position 60249: in
valid start byte

它表明问题出在60249

我去了很远的地方char-char 60249

最后一句话是

  continues the discussion of resource limits, after we've covered signals.

信号后的点是59848

有趣的是，当检查字符为64895时。

In [95]: !wc -c 07.org                 
64895 07.org

59848和64895之间的字符是真空字符。

尝试：

!cut -c59848-59848

这将立即清除我的屏幕，并将命令行向下移动到底部。
