+//! There are several cases where incorrect encoding of URLs would, in other
+//! languages, result in a parse error.
+//! In markdown, there are no errors, and URLs are normalized.
+//! In addition, unicode characters are percent encoded
+//! ([`sanitize_uri`][sanitize_uri]).
+//! For example:
+//!
+//! ```markdown
+//! <https://a👍b%>
+//! ```
+//!
+//! Yields:
+//!
+//! ```html
+//! <p><a href="https://a%F0%9F%91%8Db%25">https://a👍b%</a></p>

//! Interestingly, there are a couple of things that are valid autolinks in
//! markdown but in HTML would be valid tags, such as `<svg:rect>` and
//! `<xml:lang/>`.
