+Since Go templates are HTML-aware, `truncate` will intelligently handle normal strings vs HTML strings:
+
+```go-html-template
+{{ "<em>Keep my HTML</em>" | safeHTML | truncate 10 }} → <em>Keep my …</em>
+```
+
+{{% note %}}
+If you have a raw string that contains HTML tags you want to remain treated as HTML, you will need to convert the string to HTML using the [`safeHTML`]function before sending the value to `truncate`. Otherwise, the HTML tags will be escaped when passed through the `truncate` function.
