Audacious

I have a lot of music from all over the world, and some artist names include diacritics. Examples my include Sigur Rós, Die Ärzte or Måneskin. I would like to be able to search for those artists without having to remember how to make different diacritics on my keyboard.
For example, searching arzte should show me Die Ärtze, Ros should show Sigur Rós and Maneskin should show Måneskin.
For other projects that do that - I know that Firefox allows for strictly matching text against diacritics when searching, so this maybe could show you how they normalize the data and allow searching it like that.
