I set hide=C,Objective-C, but it doesn't seem to work.

I tried Objective%2DC based on https://www.urlencoder.org and https://en.wikipedia.org/wiki/Percent-encoding, but it did not achieve the effect.

I found that the key to the problem is ,, not -. I solved my problem by using %2C instead of , in hide=C,Objective-C.
