Try replacing the OS/2 EMX_VIDEO version of write_attributes with this
version.  I have no idea if it will work since I have no access to an
OS/2 system.  Please let me know how you make out.  Thanks, --John

static void
write_attributes (SLsmg_Char_Type *src, unsigned int count)
{
   register unsigned char *p = Line_Buffer;
   int n = count;

   /* write into a character/attribute pair */
   while (n > 0)
     {
	/* UTF8 FIXME */
	if (src->nchars)
	  {
	     SLtt_reverse_video (src->color & SLSMG_COLOR_MASK);
	     *p++ = src->wchars[0];
	  }
	else *p++ = ' ';
	*p++ = Attribute_Byte;
	n--;
	src++;
     }
   v_putline (Line_Buffer, Cursor_Col, Cursor_Row, count);
}


And here is the same thing expressed as a patch:
