Why not simply using a soft hyphen between "n" and "g" in this case ? Soft hyphens are normally recognized as such by smart correctors and as well by search engines or collators. It seems enough for me to indicate that this is not the Welsh digram "ng" ; CGJ anyway is certainly not the correct disjoiner in your case.
