### Sanitized anchor names
Blackfriday includes an algorithm for creating sanitized anchor names
corresponding to a given input text. This algorithm is used to create
anchors for headings when `AutoHeadingIDs` extension is enabled. The
algorithm has a specification, so that other packages can create
compatible anchor names and links to those anchors.
The specification is located at https://pkg.go.dev/github.com/russross/blackfriday/v2#hdr-Sanitized_Anchor_Names.
[`SanitizedAnchorName`](https://pkg.go.dev/github.com/russross/blackfriday/v2#SanitizedAnchorName) exposes this functionality, and can be used to
create compatible links to the anchor names generated by blackfriday.
This algorithm is also implemented in a small standalone package at
[`github.com/shurcooL/sanitized_anchor_name`](https://pkg.go.dev/github.com/shurcooL/sanitized_anchor_name). It can be useful for clients

// anchors for headings when AutoHeadingIDs extension is enabled. The
// algorithm is specified below, so that other packages can create

//
// The algorithm iterates over the input text, interpreted as UTF-8,
// one Unicode code point (rune) at a time. All runes that are letters (category L)
// or numbers (category N) are considered valid characters. They are mapped to
// lower case, and included in the output. All other runes are considered
// invalid characters. Invalid characters that precede the first valid character,
// as well as invalid character that follow the last valid character
// are dropped completely. All other sequences of invalid characters
// between two valid characters are replaced with a single dash character '-'.
