A couple times I've seen folks ask how to concatenate Strings. Strings in Soroban are just Bytes and their type is just a name to change how tooling might present those bytes.

Similar issue stellar/rs-soroban-sdk#1280
We might be solving it on the sdk side by leveraging bytes_append host function and the String<-> Bytes interop.

Cross-posting from stellar/rs-soroban-sdk#1280:

@jayz22 How can String convert to and from Bytes? I don't see any existing SDK functionality for converting between them, and I don't see any host functions for doing so either.
