Fix narrowing conversion in tuple_manipulator ctor

Browse Source 
This fixes unnecessary, possibly wrapping conversion of the character argument of tuple manipulators on tuple_manipulator construction. This should silence MSVC warning C4244:

  tuple_io.hpp(142,71): warning C4244:  'argument': conversion from 'const CharType' to 'const char', possible loss of data
