Invalid email validation

This email is valid: peter@häuser-bau.ch
but it can't be imported to zitadel.
I wasn't able to find this issue on GitHub. Are you aware of it and do you plan it to fix it?
Is there a workaround?

I will be in holiday, but my college will take over @Rapha

hi @Rapha just for the context, I identified that all the german umlaut words are not part of ascii and hence causing the trouble, a simple validator will fix this, I am checking with my team on what can an we do here
