PHP resolve search in the URL address bar input Chinese characters found garbled search results

The premise of this problem is that the site code in utf-8 format, PHP space when the page stays in the search page, in the browser's address bar input Chinese keyword search will appear garbled, find information on the Internet, is because the browser by default in the URL in the middle character encoded in the gb2312 format, The file encoding in my program is used in the utf-8 format, so this problem occurs, but this problem does not occur if the data submitted directly from the form is used. The workaround is as follows and requires PHP to turn on mb_string support.

if (!mb_check_encoding ($word, ' utf-8 ')) {

$word = Iconv (' gb2312 ', ' utf-8 ', $word);

}

It is so simple, recorded, convenient for later search.
