Unable to delete MoH track with invalid character

I inadvertently uploaded a MoH track with an invalid character. Clicking delete returns a white page (no menus) stating “You’re trying to use an invalid character. Please don’t.”

I suspect the track will have to be deleted in mysql somewhere, but in which table?

You’re going to have to connect to the server via ssh and erase the file.
