findepi opened a new issue #2837:
URL: https://github.com/apache/iceberg/issues/2837
For example, when bucketing string into 32 buckets, the value
`"\uD83D\uDCB0"` (`"💰"`) gets assigned a wrong bucket
### Expected bucket: 12
Per specification, string hash is `hashBytes(utf8Bytes(v))`
```
int hash =
Hashing.murmur3_32().hashBytes("\uD83D\uDCB0".getBytes(StandardCharsets.UTF_8)).asInt()
& Integer.MAX_VALUE;
int bucket = hash % 32;
System.out.println("hash = " + hash); // 661122892
System.out.println("bucket = " + bucket); // 12
```
### Actual bucket: 4
```
Integer bucket = new
org.apache.iceberg.transforms.Bucket.BucketString(32).apply("\uD83D\uDCB0");
System.out.println("bucket = " + bucket); // 4
```
### Assumed root cause
`BucketString` code:
