UTF-8 requires at most 4 bytes for single character.
So if there is some encoding that could represent those large characters
as single byte conversion to UTF-8 would require 4x bytes.
Actually this is very defensive because most characters would fit into 3
bytes according to this table:
http://en.wikipedia.org/wiki/UTF-8#Codepage_layout
So likely we can lower this to 3x, but I'm not sure.
Anyway I agree this should be documented better.
