Check return status of utf8proc_iterate. Closes #27.
If unicode parsing gives an error condition, we just skip the
rest of the string without rendering anything and proceed.
I'm not sure if that's the best way to handle this, but
garbage in, garbage out.
Note: this bug was found using american fuzzy lop.
