php - 中文字符的PHP urlencode

Answer 1

You're URLencoding using the charset you specify in your header. %D0%C2 is 新 in gb2312; %E6%96%B0 is 新 in UTF-8. Switch your charset over to UTF-8 and you should fix this issue and still be able to display Simplified Chinese Han.

Answer 2

In order to reproduce your problem I created a simple PHP file:

<?php
var_dump(urlencode('新'));
?>

First I used UTF8 encoding and got %E6%96%B0. Afterwards I changed to GB2312 and got %D0%C2.

At http://meyerweb.com/eric/tools/dencoder/ they seem to use JavaScript, that's UTF8 capable and therefore returns %E6%96%B0, too.

PS: When changing from GB2312 to UTF8 some editors might break code some internationalized code. So please make sure to have a copy of your file before converting!
