Repetition matcher fails with special UTF-8 characters #17

It seems like the repetition matcher fails to identify repetitions when composed of special UTF-8 characters like ü, for example.

Here is an example code snippet demonstrating the issue.

package main

import (
	"fmt"

	"github.com/trustelem/zxcvbn"
)

func main() {
	res := zxcvbn.PasswordStrength("aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa", nil)
	fmt.Println(res.Guesses)

	res = zxcvbn.PasswordStrength("ööööööööööööööööööööööööööööööööööööö", nil)
	fmt.Println(res.Guesses)

	res = zxcvbn.PasswordStrength("øøøøøøøøøøøøøøøøøøøøøøøøøøøøøøøøøøøøø", nil)
	fmt.Println(res.Guesses)
}
