Interesting idea, but your trick is never really going to help (you can store up to 255 bytes instead of 254). Also always using 256 bytes for every string seems wasteful.
I think LLVM's small string optimisation is always going to be a better option: https://joellaity.com/2020/01/31/string.html
22 characters is significantly less useful than 255 characters. I use this for resource name keys, asset file paths, and a few other scenarios. The max size is configurable, so I know that nothing I am going to store is ever going to require heap allocations (really bad to be doing every frame in a game engine).
I developed this specifically after benchmarking a simpler version and noticed a significant amount of time being spent in strlen(), and it had real benefits in my case.
Admittedly just storing a struct with a static buffer and separate size would have worked pretty much the same and eliminated the 255 char limitation, but it was fun to build.
