Python：读取txt时如何处理右单引号

Question

我正在使用Python读取一个包含右单引号的txt:'

ord("’")
Out[46]: 8217

1. 如何输入'？我发现我只能输入'
2. 如何阅读“as”
3. 我对这两个字符的理解是：“是Unicode”和“是ASCII”？是这样吗

http://www.fileformat.info/info/unicode/char/2019/index.html 我正在使用以下代码读取txt文件：

with open(text_path, 'r', encoding='utf-8') as f:
    transcript = f.read()

Answer 1

您可以编写一个自定义编码函数，将utf-8字符转换为查找表中指定的ascii字符

# -*- coding: utf-8 -*-
import io

def encode_file(filepath, conversion_table={}):

    ''' replaces utf-8 chars with specified equivalent ascii char'''

    with io.open(text_path, "r", encoding="utf-8") as f:
        transcript = f.read()

    new_transcript = ""
    for i in transcript:
        new_char = ""
        # append character if ascii
        try:
            new_transcript += i.encode("ascii")
        except UnicodeEncodeError:
            found_char = False
            for c in conversion_table:
                # replace utf-8 with custom ascii equivalent
                if i == unicode(c, encoding="utf-8"):
                    new_transcript += conversion_table[c]
                    found_char = True
            # no conversion found
            if found_char == False:
                new_transcript += "?"
    return new_transcript

text_path = "/path/to/file.txt"
conversion_table = {'ü':'u', 'ô':'o', 'é':'e', 'į':'i'}
print (encode_file(text_path, conversion_table))

例如，如果文件的内容为my ünicôdé strįng，则会产生my unicode string

因此，您可以将'’':'\''（或任何转换）添加到conversion_table，它将为您进行替换
