But, if we move core and Parsoid to HTML5 ids, this shouldn't matter since the only restriction on HTML5 ids is that they shouldn't contain a space char as per https://html.spec.whatwg.org/multipage/dom.html#the-id-attribute
You would still have to output the legacy anchor as well, unless you want to break existing links.
Anyway I wasn't thinking of character sets but problems like https://phabricator.wikimedia.org/T26262. But maybe I am confusing things and section anchors handle those correctly and only the post-edit redirection ID fragment does not.
