I think instead of :? this should use .to_str() on the pointer received to avoid Rust-level string escaping which shows up in the debug representation.

.to_str() leaves me with the potential to get a Utf8Error instead of a &str. I was not sure what the preferred way to deal with such bad input would be, but based on what I see in crates/c-api/src/trap.rs, I think I will go with String::from_utf8_lossy(). Sound good?

Yeah I think the _lossy variant is fine. That's a reality of working with cross-language FFI here but in the context of "just an error message" the lossy variant should be fine.
