APplying the following function:
void
remove_non_graph(std::string& str)
{
  for(std::string::iterator i=str.end()-1; i>=str.begin(); --i)
  {
     if ( !isalnum(*i) && !isgraph(*i) )
     {
       str.erase(i);
     }
   }
}
to a variable fixes the issue.

Do you think this is a solid patch?
If so, where in the source codes, should I add it so that all the
variables are cleaned this way?

Thanks!
