我认为，解决您问题的唯一方法是编写自己的重写模块.这些文章可能会有所帮助:

I think the only solution for your problem is to write your own Rewrite Module. These article might help:

我无法对其进行测试，但如果采用这种方法，我就无法测试，但可以使用另一个正则表达式进行尝试:

I cannot test it and I'm not if it works that way, but try it with another regular expression:

((%20)|\ )+

例如，应将类似于此 http://www.goo%20le.de/hfdhdhdhd 的网址替换为该 http://www.goo-le.de-/-hfdhdhdhd

For example an Url like this http://www.goo%20le.de / hfdhdhdhd should be replaced to this http://www.goo-le.de-/-hfdhdhdhd
