问题
When I enter ë into a form on my web application, this is percent encoded by Google Chrome to %C3%AB.
When I use PHP's urlencode('ë'); This is encoded into %EB.
Why are the encodings different?
How can I encode with the same encoding as Google Chrome with PHP 4?
回答1:
%EB is the ISO-8859-1 form (a single character).
%C3%AB is the UTF-8 form (e + ¨).
It should work out of the box (if you use a newer version of PHP and UTF-8 for your files).
