How do I exclude mb_* functions from my scoper-autoload?

[hirasso]

Hi there! I have an issue where I'm not sure if its a bug. In my scoper-autoload.php, I get all these mb_* functions, even though these will never be in my scoped vendor namespace. Aren't those built-in PHP functions?

I think it deserves a doc entry because I've been confused by it myself more than once.

I don't remember exactly under what condition this happens, but I recall this was to add native support for polyfills which in essence is declaring built-in symbols.

Granted it looks a bit ugly, but it should not cause issues
