Hello, Michal! The functions for getting the length in bytes and the functions for getting the length of a string in characters are different functions for different tasks. That is, `mb_strlen` is not equivalent to `strlen` and cannot replace it: ``` $string = ‘Hell 😁 or 😎 world!’; echo ‘Bytes: ’ . \strlen($string) . "\n"; echo ‘Chars: ‘ . \mb_strlen($string); ``` When you work with data: sockets, row sizes in the database, shared memory, and so on, you operate with bytes. And the size in characters is rarely required, for example, to format the output in the console (with utf support). So answering your question about "when" - the answer is simple: This will never be done, because these are functions for different tasks ;) -- Kirill Nesmeyanov
