Support configurable anchor slug style (e.g., "Zettlr‑style" stripping emojis/symbols) #414
Description
Description:
Currently, Marksman generates heading anchors following GitHub‑style slugs, preserving emojis/symbols:
## ⏸️🖥️ Break during work
→ becomes #⏸️🖥️-break-during-work
However, tools like Zettlr strip emojis and special characters—producing: #break-during-work
This mismatch breaks cross-tool clickable anchor links.
No existing issue appears in the repo concerning slug behavior.
Proposal:
Introduce a boolean configuration, e.g., slug_style = "zettlr" or strip_emojis = true, to allow users to generate sanitized anchors (lowercase, ASCII alphanumeric + hyphens).
Could be supported via CLI flag (--zettlr-anchors) or LSP server setting.
Steps / Implementation Sketch:
Modify slug generation (e.g., in lib/slug.rs) to optionally strip emojis and non-alphanumeric characters
Add config option in features.md
Add tests: emojis removed, slug matches break-during-work
Benefits:
Improves interoperability with Zettlr and other sanitized‑slug tools
Users can consistent linking across editors
