>Note: Unfortunately it's not recommended to set this an an `.htaccess` file as this may lead to undefined behavior.

When mbstring function overloading is turned on the built-in PHP function `strlen()` counts Unicode characters, not bytes, and the change can break existing code. Use `mb_string($str, 'ISO-8859-1')` to find the byte length of `$str`.
