    tests: fix test_big_char() test when running with uchardet.
    
    We send two 3-bytes UTF-8 characters to the output stream, by write
    chunks of 2 bytes. Let's feed at least a complete character to uchardet
    to have a relevant answer.
    Right now it was returning WINDOWS-1252 (which is a valid answer with
    the 2 bytes it was given).
