Generates a printed representation of the date, in a
localesetlocale-specific way.
Works just like the platform's C library strftime() function,
but only accepts date-related formats; time-related formats
give undefined results. Date must be valid. Unlike strftime()
(which uses the locale encoding), works on a UTF-8 format
string and stores a UTF-8 result.
This function does not provide any conversion specifiers in
addition to those implemented by the platform's C library.
For example, don't expect that using Date.strftime would
make the \F provided by the C99 strftime() work on Windows
where the C library only complies to C89.
