Hey, I noticed that current implementation is differs from original C implementation on emojis. This might be a problem for multilingual systems.
Example with the string from Readme:
#include <stdio.h>
unsigned long hash(unsigned char *str) {
unsigned long hash = 5381;
int c;
while ((c = *str++))
hash = ((hash << 5) + hash) ^ c;
return hash & 0xFFFFFFFF;
}
int main() {
unsigned char myString [] = "🦄🌈";
printf("hash %ld\n", hash(myString));
return 0;
}
// => hash 1642026147

DJB2a non-cryptographic hash function
