PR isn't merged yet! I assume it will be :-)

I assume it's ok if devs create PRs for content like this? I'd like to give it a go, if so, but not sure of the process here. I'm going to add to our team project to track anyway.

Here's the suggested content:

---

EncodeURI

The EncodeURI lambda will evaluate the text passed by returning the value of the encodeURI() function applied to the text.

For example, when the Mustache variable context.url is https://example.com?query=foo bar (note the embedded space), the following template will render as https://example.com?query=foo%20bar:

{{#EncodeURI}}{{{context.url}}}{{/EncodeURI}}

Note that unlike most lambdas that trim whitespace, this lambda does not. If there is whitespace after {{#EncodeURI}} or before {{/EncodeURI}}, those characters will be encoded in the result.

EncodeURIComponent

The EncodeURIComponent lambda will evaluate the text passed by returning the value of the encodeURIComponent() function applied to the text.

For example, when the Mustache variable context.url is https://example.com?query=foo bar (note the embedded space), the following template will render as https%3A%2F%2Fwww.elastic.co%3Ffoo%3Dbar%26baz%3D%20qux:

{{#EncodeURIComponent}}{{{context.url}}}{{/EncodeURIComponent}}

Note that unlike most lambdas that trim whitespace, this lambda does not. If there is whitespace after {{#EncodeURI}} or before {{/EncodeURI}}, those characters will be encoded in the result.
