Indeed — I can see that would be the correct way. But unfortunately it isn’t as simple: Lua strings are immutable, so it wouldn’t be good enough to have strings represented by byte[] (the contents of the array are mutable in Java), and there is no ByteString or equivalent in the JDK.

So far I went with java.lang.String since it’s ubiquitous in the Java world, (plus Strings may be interned by the JVM), so I thought it would be good for Java interop. But it might be the time to face the issue, and roll my own ByteString for 100% correctness.

That would be very helpful! Let me know if I can help with anything!
