UnicodeDecodeError：'ascii'编解码器无法解码位置0中的字节0xe2：序号不在范围内（128）

Question

我有这个代码：

# -*- coding: utf-8 -*-

forbiddenWords=['for', 'and', 'nor', 'but', 'or', 'yet', 'so', 'not', 'a', 'the', 'an', 'of', 'in', 'to', 'for', 'with', 'on', 'at', 'from', 'by', 'about', 'as']


def IntoSentences(paragraph):
    paragraph = paragraph.replace("–", "-")
    import nltk.data
    sent_detector = nltk.data.load('tokenizers/punkt/english.pickle')
    sentenceList = sent_detector.tokenize(paragraph.strip())
    return sentenceList

from Tkinter import *

root = Tk()

var = StringVar()
label = Label( root, textvariable=var)
var.set("Fill in the caps: ")
label.pack()

text = Text(root)
text.pack()

button=Button(root, text ="Create text with caps.", command =lambda: IntoSentences(text.get(1.0,END)))
button.pack()

root.mainloop()

当我运行代码时，一切正常。 然后我插入文本并按下按钮。 但后来我得到了这个错误：

C:\Users\Indrek>caps_main.py
Exception in Tkinter callback
Traceback (most recent call last):
  File "C:\Python27\lib\lib-tk\Tkinter.py", line 1470, in __call__
    return self.func(*args)
  File "C:\Python27\Myprojects\caps_main.py", line 25, in <lambda>
    button=Button(root, text ="Create text with caps.", command =lambda: IntoSen
tences(text.get(1.0,END)))
  File "C:\Python27\Myprojects\caps_main.py", line 7, in IntoSentences
    paragraph = paragraph.replace("ŌĆō", "-")
UnicodeDecodeError: 'ascii' codec can't decode byte 0xe2 in position 0: ordinal
not in range(128)

如何解决这个问题？ 起初我有相同的错误消息，当我尝试运行代码，然后我添加了lambda：现在当我点击我的应用程序中的按钮时出现问题。

您必须将字符串解码为utf-8（或其他一些编码），然后将unicode字符串替换为其他字符串。 这段代码完成了您要实现的目标：

paragraph = paragrah.decode('utf-8').replace(u'\u014c\u0106\u014d','-')
# '\u014c\u0106\u014d' is the unicode representation of characters ŌĆō
