Create a string that containing the characters from the specified range. Optionally specify a basicAllocator used to supply memory. If basicAllocator is not specified, a default-constructed allocator is used. Note that range must meet the requirements of an input range and the values from range must have a type matching or convertible to (template parameter) CHAR_TYPE.
