我在理解文本读取和写入文件时遇到了一些大脑失败(Python 2.4).

# The string, which has an a-acute in it.
ss = u'Capit\xe1n'
ss8 = ss.encode('utf8')
repr(ss), repr(ss8)

("u'Capit\xe1n'","'Capit\xc3\xa1n'")

print ss, ss8
print >> open('f1','w'), ss8

>>> file('f1').read()
'Capit\xc3\xa1n\n'

所以我输入Capit\xc3\xa1n我最喜欢的编辑器,在文件f2中.

然后:

>>> open('f1').read()
'Capit\xc3\xa1n\n'
>>> open('f2').read()
'Capit\\xc3\\xa1n\n'
>>> open('f1').read().decode('utf8')
u'Capit\xe1n\n'
>>> open('f2').read().decode('utf8')
u'Capit\\xc3\\xa1n\n'

我在这里不理解什么？显然,我缺少一些重要的魔法(或者很有道理).在文本文件中键入什么来获得正确的转换？

我真正没有想到的是,UTF-8表示的重点是,如果你真的不能让Python识别它,那么它来自外部.也许我应该只是JSON转储字符串,并使用它,因为它有一个asciiable表示!更重要的是,当从文件进入时,Python会识别和解码这个Unicode对象的ASCII表示吗？如果是这样,我怎么得到它？

>>> print simplejson.dumps(ss)
'"Capit\u00e1n"'
>>> print >> file('f3','w'), simplejson.dumps(ss)
>>> simplejson.load(open('f3'))
u'Capit\xe1n'
