/* there needs to be support for Unicode here,

* algorithm for multi-byte characters (perhaps
* by adding every four 16-bit characters and
* shortening the sum to 32 bits). Otherwise
* I suggest performing MD-5 as if every character
* was two bytes--e.g., 0040 0025 = @%--but then
* how will an ordinary MD-5 sum be matched?
* There is no way to standardize text to something
* like UTF-8 before transformation; speed cost is
* utterly prohibitive. The JavaScript standard
* itself needs to look at this: it should start
* providing access to strings as preformed UTF-8
* 8-bit unsigned value arrays.
