Unfortunately, there are no mechanisms in Mathematica's Export function
for specifying set names. You may want to use a tool like NCSA's hdfed to
add the desired set names.

If you are working with an eight-bit character encoding, you could transform
the string into an array of characters (e.g. like what is returned by the
built-in Characters function) and then write out the array as Byte data
