Calculate a signed Java string hash for text-seed experiments.

Signed Java string hash1444183289

This is a string hash, not a world generator or numeric-seed converter.

Java String.hashCode

This implements the signed 32-bit hash of Java UTF-16 characters. It is useful when exploring text-based world seeds and reproducing Java string hashes.

A hash is not a world preview

This does not reproduce numeric-seed parsing, every Minecraft version’s seed handling, terrain generation or a world map. Different strings can produce the same hash.
