OK, thank you for the feedback, I think the problem is with the flatten method, I'll change it to see if it works in a non-Latin alphabet. https://github.com/Kunzisoft/KeePassDX/blob/master/app/src/main/java/com/kunzisoft/keepass/utils/StringUtil.kt

The results can be searched, but a significant delay can be felt.

OK, that's what I thought, so I'll remove the accent removal feature , it takes too much time and can't be implemented without having a side effect. #945
