Sure, it isn't the most affordable sollution but it's worth it at the higher levels. Considering at level 20 you would only need to roll a 2 or more to affect a CR 20 creature, it seems pretty reasonable. Then add on top of that the other various ways you have to boost your truenaming skill and you should be good to go.
Granted at lower levels before you can afford the skill boosting item you'd be out of luck, but it's something at least.
