    source=("a".."z").to_a + ("A".."Z").to_a + (0..9).to_a + ["_","-","."]

´Hey Femoco,

Thank you! This was really useful. Though, when I tried to use it to generate a string with repetitive letters it won't work. It seems it does not generate a string with repetitive letters, do you imagine why?
