Hey thanks for the heads up. On my end that character appears differently; it should be an Umlaut. Are you in a non-Windows OS by chance?
I will be prepared to make an emergency re upload if needed today... hopefully it's just a one off issue due.
Edit: sorry I deleted the original comment somehow and am not sure how to un-delete it.
For context, Life is Cancer reported an issue in which BGM file names had an errant Russian character that was causing a crash.
