Polyfill for pmmp/ext-encoding

This library provides a polyfill implementing the API of pmmp/ext-encoding.

This can be used in environments where the extension is not available.

Warning

This polyfill is slow. It's 5-10x slower than the native extension, similar to pmmp/BinaryUtils (which is used to provide the underlying functionality).

You should consider adding the extension to your PHP binary instead of using this polyfill.

Only use this if installing the extension is not an option for some reason.
