Stuck in unesacpe ----- -- WEB400

Afternoon all,

        I am sitting here attempting to get an ILE-C routine to work and
having some issues with the unescape code !

        Test Message from the HTML (code) to see what unescape [will] do
with the characters..

        Results in this ---

        Test Message from the HTML  code� to see what unescape qwillr do
with the characters..

        Note that ( ) [ ] are lost / mistranslated....in the routine x2c().
        Using  a standard cgilib.c (below) from the web, and I have
attempted translating back to ascii in the routine with the same results...

        Any direction ????  Rewrite ??
