The second overload of this function allows to convert a string of the given
length @e inLen, whether it is @c NUL-terminated or not (for wide character
strings, unlike for the multibyte ones, a single @c NUL is always enough).
But notice that just as with @ref wxMBConv::mb2wc cMB2WC, it is more
efficient to pass an already terminated string to this function as otherwise a
copy is made internally.
