Invalid domain bug

Hello. Sorry about this issue everyone. I don’t believe this is something that the pihole needs to be concerned about and said as much in the ticket. Thank you for all the information @Bucking_Horn, that is really useful.

Although I primarily use my hosts formatted list with the pihole, I also use it with uBlock Matrix, and I know others use it with uBlock Origin and still more tools. It’s completely makes sense that the pihole only needs to know the puny code version- I’m not sure about browser extensions. If someone has any information that all the ads blockers out there only need punycode versions, then I believe having both versions in the list provides the most coverage.

So:

  1. all maintainers remove IDNs from their lists (unrealistic)

As much as I like pihole, it’s not the only tool that accepts hosts formatted lists.

  1. pihole converts IDNs to punycode (wast of resources)

I’m not against this, but I also don’t think it’s necessary as I added both versions.

  1. keep it as it is (generates support requests)

Yes. Perhaps someone will have some information for me about browser extensions and I can just remove the domains causing the complaints.
