SDL_isgraph - Report if a character is any "printable" except space.

       This function is available since SDL 3.2.0.

       Be advised that "printable" has a definition that goes back to text terminals from the dawn of computing,
       making  this  a  sort  of  special  case  function  that  is  not suitable for Unicode (or most any) text
       management.

       WARNING: Regardless of system locale, this is equivalent to (SDL_isprint(x))&&((x)!='').

x      character value to check.

       SDL_isgraph - Report if a character is any "printable" except space.

       Returns non-zero if x falls within the character class, zero otherwise.
