Most functions simply treat strings as sequences of bytes assuming that each character takes up exactly one byte. This behaviour still allows for storing UTF-8 encoded text in PHP strings but many operations on strings have unexpected results. To circumvent this problem we have created some alternative functions to PHP's native string operations which use code points instead of bytes. These functions can be found in <code>/includes/utf/utf_tools.php</code>. They are also covered in the <a href="http://area51.phpbb.com/docs/code/">phpBB3 Sourcecode Documentation</a>. A lot of native PHP functions still work with UTF-8 as long as you stick to certain restrictions. For example <code>explode</code> still works as long as the first and the last character of the delimiter string are ASCII characters.</p> |
