Narrow char.
This virtual function converts the char to char using the simplest reasonable transformation. If the conversion fails, dfault is returned instead. For an underived ctype<char> facet, c will be returned unchanged.
do_narrow() is a hook for a derived facet to change the behavior of narrowing. do_narrow() must always return the same result for the same input.
Note: this is not what you want for codepage conversions. See codecvt for that.

Narrow char array to char array.
This virtual function converts each char in the range [lo,hi) to char using the simplest reasonable transformation and writes the results to the destination array. For any char in the input that cannot be converted, dfault is used instead. For an underived ctype<char> facet, the argument will be copied unchanged.

Return a mask array.
This function finds the mask for each char in the range [lo, hi) and successively writes it to vec. vec must have as many elements as the char array.
