Change it to Ptr{Char} (Char is 4 bytes) instead of Ptr{Int32}, in order to
save yourself from making a copy of the data.
Beware that this code may not be portable, if the C library you are using
employs the wchar_t type. If you want it to work on Windows, too, you may
need to deal with UTF16 on that system. (You could have two versions of
the function, depending on sizeof(Cwchar_t).)
