char_type widen(char c )const;

Converts a character c to its equivalent in the current locale. The result is converted from char to character type used within the stream if needed.

Effectively calls std::use_facet<std::ctype<char_type>>(getloc()).widen(c).

Parameters

character to convert

Return value

Character converted to char_type
