Incorrect Unicode input on Windows Console

To reproduce:

• start a windows console

• change the console's font to a ttf unicode font, like "Lucida Console".

• type "chcp 65001" to set it to the UTF-8 code page.

• start ghci (same error appears when running compiled executable)

• > import System.IO (or GHC.IO.Handle)

• > enc <- mkTextEncoding "UTF8"

• > hSetEncoding stdin enc

• > getLine

• > Фывфыв (or any international unicode sequence)

• ** Exception: <stdin>: hGetLine: end of file
