Do people ever invent new characters in the modern era?

I know some have been invented for cantonese specifically, I don't know how long ago.

But are people inventing any new words that are not the result of compounding existing characters?

To give an example of what I'm thinking about, when cellphones came about they named them 手機 = "hand machine".

This alternate idea would be just creating a phonetic name for it and then creating a new character for it, without involving existing ones. If a phone was called rì, maybe the character could be 日 with a hand radical to its left, etc.

It's not that I'm suggesting chinese people should be doing this instead or anything, I'm just curious if it happens. I have the impression that other languages can create new words constantly without necessarily having to combine morphemes from others.
