> The algorith for cologne phonetic is (simpilied):
>  # Encode letter by letter from left to right according to the conversion table.
>  # Remove all digits occurring more than once next to each other.
>  # Remove all code "0" except at the beginning.
> Characters which are not specified in conversion table (such as hyphens) are ignored. See https://en.wikipedia.org/wiki/Cologne_phonetics
> If the input is "test-test" the step results will be:
>  # 20822082
>  # 2082082
>  # 28282
> The expected result for "test-test" is therefor 28282.
> The actual result for "test-test" is 282{color:#FF0000}2{color}82.
> This bug is caused by the fix from
