-
-The `transform.HTMLUnescape` function replaces [HTML entities] with their corresponding characters.
-
-```go-html-template
-{{ htmlUnescape "Lilo & Stitch" }} → Lilo & Stitch
-{{ htmlUnescape "7 > 6" }} → 7 > 6
-```
-
-In most contexts Go's [html/template] package will escape special characters. To bypass this behavior, pass the unescaped string through the [`safeHTML`] function.
-
-```go-html-template
-{{ htmlUnescape "Lilo & Stitch" | safeHTML }}
-```
