# `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.
|
|
|
|
|
|

|
|
|
