+In contrast with `strings.CountRunes` function, which strips HTML and whitespace before counting runes, `strings.RuneCount` simply counts all the runes in a string. It relies on the Go [`utf8.RuneCountInString`] function.
+
+```
+{{ "Hello, 世界" | strings.RuneCount }}
+<!-- outputs a content length of 9 runes. -->
+```
