All of getpos, col, vim.current.window.cursor report wrong col number on multibyte line

[Angri]

They calculate col number counting bytes, not chars.

Also :python vim.current.line and :python vim.current.buffer holds
data in strings encoded in utf-8, but it should be python unicode
objects, I think.
