Details

For many operations, strlen may suffice. However; with non-English localization and accented player names, strlen may not return the correct amount of characters.

Non-accented Latin Characters:

print("Count:", strlen("The Lich King")) -- Count: 13
print("Count:", strlenutf8("The Lich King")) -- Count: 13

Accented Latin Characters:

print("Count:", strlen("Der Lichkönig")) -- Count: 14 (incorrect)
print("Count:", strlenutf8("Der Lichkönig")) -- Count: 13
