data will be retrieved. This is an integer number of
characters from the beginning of the text buffer. The first
character position is 0 (zero).
num_chars Specifies the number of wchar_t characters to be copied into
the provided buffer.
buffer_size
Specifies the size of the supplied buffer as a number of
wchar_t storage locations. The minimum size is num_chars + 1.
