Duplicate UUIDs - V5 inconsistencies when using UTF8/Unicode characters

[vjamrich]

Two different input names can result in the same v5 UUID - e.g. 人 & 人 will both be encoded to f7cd5579-8db4-5043-bd83-98565a62a4f4
This is caused by the v5 not working properly with UTF8 characters.

Dart

import "package:uuid/uuid.dart";
final String key = const Uuid().v5(Uuid.NAMESPACE_X500, "人");
print(key);

Output: f7cd5579-8db4-5043-bd83-98565a62a4f4

Python

import uuid
key = uuid.uuid5(
    namespace=uuid.NAMESPACE_X500,
    name="人",
)
print(key)

Output: 3af28677-8030-59ef-81a6-051ddf226fad

Expected Output

The output String should be consistent.

The fix is now part of the v4.4.0 release, sorry for the delay, there were other problems I had to fix due other problems fixed as part of the release.
