Flowreader has

some problem with most non-English links!

e.g I click on one non-English link in my flowreader account :

http://rightman.ir/%25D8%25A8%25D9%2588%25D8%25B1%25D8%25B3%25DB%258C%25D9%2587-%25D8%25AA%25D8%25AD%25D8%25B5%25DB%258C%25D9%2584%25DB%258C-%25D9%2588%25D8%25B2%25D8%25A7%25D8%25B1%25D8%25AA-%25D8%25B9%25D9%2584%25D9%2588%25D9%2585-%25D8%25AF%25DA%25A9%25D8%25AA%25D8%25B1%25DB%258C-%25D8%25AC%25D8%25B0%25D8%25A8/

The flowreader redirects me to "Page not found! "

But the real link is :http://rightman.ir/%D8%A8%D9%88%D8%B1%D8%B3%DB%8C%D9%87-%D8%AA%D8%AD%D8%B5%DB%8C%D9%84%DB%8C-%D9%88%D8%B2%D8%A7%D8%B1%D8%AA-%D8%B9%D9%84%D9%88%D9%85-%D8%AF%DA%A9%D8%AA%D8%B1%DB%8C-%D8%AC%D8%B0%D8%A8/

Is have same errors for some other website links such as:

https://news.asis.io/content/%25DA%25A9%25D8%25B4%25D9%2581-%25D8%25A2%25D8%25B3%25DB%258C%25D8%25A8%25E2%2580%258E%25D9%25BE%25D8%25B0%25DB%258C%25D8%25B1%25DB%258C%25E2%2580%258E%25D9%2587%25D8%25A7%25DB%258C-%25D8%25AC%25D8%25AF%25DB%258C-%25D8%25AF%25D8%25B1-%25D8%25B3%25D8%25A7%25D9%2585%25D8%25A7%25D9%2586%25D9%2587-%25D8%25A8%25D9%2587%25E2%2580%258E%25D8%25B1%25D9%2588%25D8%25B2%25D8%25B1%25D8%25B3%25D8%25A7%25D9%2586%25DB%258C-plsql-developer

But some non-English links like http://www.aftana.ir/fa/doc/news/11134/%25D8%25AD%25D9%2585%25D9%2584%25D9%2587-%25D9%2587%25DA%25A9%25D8%25B1%25D9%2587%25D8%25A7-%25D8%25B3%25DB%258C%25D8%25B3%25D8%25AA%25D9%2585-%25D9%2587%25D8%25A7%25DB%258C-%25D8%25AD%25D8%25B3%25D8%25A7%25D8%25B3-%25DB%258C%25DA%25A9-%25D8%25B4%25D8%25B1%25DA%25A9%25D8%25AA-%25D8%25AA%25D8%25A3%25D9%2585%25DB%258C%25D9%2586-%25DA%25A9%25D9%2586%25D9%2586%25D8%25AF%25D9%2587-%25D8%25A2%25D8%25A8-%25D8%25A8%25D8%25B1%25D9%2582
