我有一组python脚本(https://github.com/hvdwolf/wikiscripts),可以解析wikidumps,使其成为gpx/osm/csv/sql/sqlite转储,用作Nav应用程序中的POI文件。我只分析有坐标的文章。为此,我使用包含SQLINSERT语句的externallinks转储。包含“”的sql语句地理黑客.php“子字符串不包含坐标。我将这些导入sqlite数据库中,作为文章转储的参考。 它们都是utf-8转储文件,解析所有“西式”文件都可以正常工作,但阿拉伯语、波斯语、俄语、日语、希腊语、汉语和其他语言都不起作用。显然我做错了什么。你知道吗
我得到的标题字符串是:
%D9%85%D8%A7%D9%81%D8%B8%D8%A9_%D8%A7%D9%84%D8%A8%D8%AF%D8%A7%D8%A6%D8%B9 %D8%A3%D9%88%D8%B1%D9%8A%D9%88%D9%8A%D9%84%D8%A7 Battle_of_Nicopolis
Qingdao
所以一些正常的字符是可以的。其余的都是胡言乱语(对我来说)。 我已经做了一些测试,只需读取转储并写入utf-8编码的文本文件(line-in=>;line-out),然后就可以正常工作了,但是在字符串处理函数和“re.”函数的某个地方,它会更改我的unicode文本。你知道吗
编辑:我的python脚本以:#--编码:utf-8--
我的代码(相关部分,包括python2和python3语句,以及一些用于显示我已经尝试的内容的注释):

看起来标题是percent-encoded。你知道吗
