Redirection issue with Japanese characters in query string on static front page

[jomgapuz]

Hello,

I have found a bug that when a static page option is enabled from here:
​http://jom.x10.mx/wp-admin/options-reading.php

Then, you accessed the home page with the Japanese characters on the query string, it causes redirection issues “ERR_TOO_MANY_REDIRECTS”.

Example links are:

​http://jom.x10.mx/index.php?%E3%82%B6%E3%82%AF%E2%85%A1F%E5%9E%8B%EF%BC%88%E7%A0%B2%E6%92%83%E8%A3%85%E5%82%99%EF%BC%89

You can test this on any self hosted WordPress installation with the “static page” option enabled. This causes our client’s SERP to have been ruined.

I think we need to stop WordPress processing and filtering query string to cause redirection. This will also cause performance issues.
