# `strrev` Function

`strrev` reverses the characters in a string.
Note that the characters are treated as _Unicode characters_ (in technical terms, Unicode [grapheme cluster boundaries](https://unicode.org/reports/tr29/#Grapheme_Cluster_Boundaries) are respected).

```hcl
strrev(string)
```

## Examples

```shell-session
> strrev("hello")
olleh
> strrev("a ☃")
☃ a
```
