Hi!

Am I correct that this library is being used by GitHub for rendering README.md's and for heading slug generation? Or is https://github.com/kivikakk/comrak actually getting used for this?

There are a lot of quirks in this slug generation (e.g. how punctuation / emojis / hash-sign / cyrillic / latin-1 / spaces are getting replaced by hyphens and if multiple hyphens get contracted to a single hyphen in the middle/beginning/end of slug), but being able to replicate it exactly is important sometimes (for Markdown generation and generating ToC's / links to certain headings)

Thank you :)
