[encoding] Benefits of "Legacy" Encodings – Byte Counter (#4)

Hi, I appreciate UTF family encodings enforcement in `TextEncoder`, but the "legacy" ones might be needed in some situations. I created this thread to demonstrate one and ask your opinion.

I have come across a problem which probably cannot be solved without "legacy" encodings support – byte counting of a text in its original encoding. I need to count bytes of a text in `<textarea>` as if it was in *windows-1250*, *koi8-u*... Do you happen to know how to count it, please?
