continuous-integration/drone/push Build is failingDetails
Turns out I fixed the crash, but some unicode-characters were not
lower-cased. I'm using ICU now. It is very easy, makes sense and is
all-around pleasant.
Converting some text to lowercase caused range errors. I don't really
know what I'm doing here, so I replaced the code with this answer from
StackOverflow: <https://stackoverflow.com/a/21395>. It works now,
let's hope it stays that way.
