An example where the half star appears in the middle of text would be helpful, e.g. "Die Hard 7 ( 1/2*) is the latest movie..." In most of the examples I have, the stars are kind of on their own rather than in the flow of text, and that makes a difference to the Unicode committee.
If you have good examples, you can email my username @righto.com
