当我们这样建立文件时

f = file('x1.txt', 'w')

f.write(u'中文')

f.close()

直接结果应该是类似

f.write(u'中文')

UnicodeEncodeError: 'ascii' codec can't encode characters in position 0-16: ordinal not in range(128)

要直接写 utf-8 文件怎么办呢?

import codecs

f = codecs.open("pru_uni.txt", "w", "utf-8")

txt = unicode("campeón\n", "utf-8")

f.write(txt)

f.write(u'中文\n')

f.close()
