+# `urlencode` Function
+
+`urlencode` applies URL encoding to a given string.
+
+This function identifies characters in the given string that would have a
+special meaning when included as a query string argument in a URL and
+escapes them using
+[RFC 3986 "percent encoding"](https://tools.ietf.org/html/rfc3986#section-2.1).
+
+The exact set of characters escaped may change over time, but the result
+is guaranteed to be interpolatable into a query string argument without
+inadvertently introducing additional delimiters.
+
+If the given string contains non-ASCII characters, these are first encoded as
+UTF-8 and then percent encoding is applied separately to each UTF-8 byte.
+
+## Examples
+
+```
+> urlencode("Hello World")
+Hello%20World
+> urlencode("☃")
+%E2%98%83
+> "http://example.com/search?q=${urlencode("terraform urlencode")}"
+http://example.com/search?q=terraform+urlencode
+```
