Unicode

[bordoley]

OCaml's Unicode support appears to be fairly abysmal, and I'm a little concerned that bs-containers is not improving the situation. Perhaps we should remove the char and string modules altogether and encourage use of native javascript strings in bucklescript and let native users adopt libraries like Camomille etc.

Or we can implement a reasonable utf8 module inside bs-core, redirect the user to js native utf8 if they are compiling to js and provide a native implementation of our own.

note javascript strings are UCS-2(essentially UTF-16) according to spec http://sking7.github.io/articles/131730713.html.

Apart from the fact that OCaml has little support for utf8, I still think bs-core/bs-containers should have a char/string module as the stdlib char/string module is currently lacking. As stated before I think bs-containers as a stdlib candidate should support provide better support for char/string, and deal the Unicode issue with some other utilities.
