link (a href) is removed when contain _

I have text like that:

<a href="example_example.domain.com">some text</a>

and after htmlpurifier I get:

<a href="">some text</a>

After some investigation, I find put that when url contain _ then whole url is removed. Can I set something in coinfig to allow link contains char _ ?

Two things: 1. the link you've written is missing http:// so it wouldn't point to the real website anyway and it certainly should not have been filtered in the way you suggest, 2. underscore isn't a valid character in URL domains which is why it's been filtered out. There isn't (currently) a way to disable this behavior.

Any update on this, local subdomains can technically contain underscores.
