从字符串中删除每个非utf-8符号 [英] Delete every non utf-8 symbols from string

问题描述

我有大量的文件和解析器.我要做的是剥离所有非utf-8符号并将数据放入mongodb中. 目前，我有这样的代码.

I have a big amount of files and parser. What I Have to do is strip all non utf-8 symbols and put data in mongodb. Currently I have code like this.

with open(fname, "r") as fp:
    for line in fp:
        line = line.strip()
        line = line.decode('utf-8', 'ignore')
        line = line.encode('utf-8', 'ignore')

我仍然会收到错误消息

bson.errors.InvalidStringData: strings in documents must be valid UTF-8: 
1/b62010montecassianomcir\xe2\x86\x90ta0\xe2\x86\x90008923304320733/290066010401040101506055soccorin

我不明白.有一些简单的方法可以做到吗?

I don't get it. Is there some simple way to do it?

UPD :似乎Python和Mongo对Utf-8有效字符串的定义并不相同.

UPD: seems like Python and Mongo don't agree about definition of Utf-8 Valid string.

推荐答案

请尝试在下面的代码行而不是最后两行.希望对您有所帮助:

Try below code line instead of last two lines. Hope it helps:

line=line.decode('utf-8','ignore').encode("utf-8")
