| # `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+World%21 |
| > urlencode("☃") |
| %E2%98%83 |
| > "http://example.com/search?q=${urlencode("terraform urlencode")}" |
| http://example.com/search?q=terraform+urlencode |
| ``` |
