Heading anchors now keep the same characters as GitHub: letters, marks, decimal and letter numbers, connector punctuation and alphabetic symbols, with ASCII spaces turned into `-`. The rule follows [github-slugger](https://github.com/Flet/github-slugger), whose fixtures are generated from real GitHub renders. - Other whitespace, including newlines in multi-line headings, is dropped instead of becoming `-`, so `1<em space>ab` gets `#1ab` - Combining marks are kept, so `हिन्दी` no longer becomes `हनद` - Other numbers like `²` and `①` are dropped Fixes https://github.com/go-gitea/gitea/issues/27754 This PR was written with Claude Code. --------- Co-authored-by: Claude Opus 5.5 <noreply@anthropic.com> Co-authored-by: silverwind <me@silverwind.io>
