This rule is triggered whenever a URL or email address appears without
surrounding angle brackets:

```markdown
For more info, visit https://www.example.com/ or email user@example.com.
```

To fix this, add angle brackets around the URL or email address:

```markdown
For more info, visit <https://www.example.com/> or email <user@example.com>.
```

If a URL or email address contains non-ASCII characters, it may be not be
handled as intended even when angle brackets are present. In such cases,
[percent-encoding](https://en.m.wikipedia.org/wiki/Percent-encoding) can be used
to comply with the required syntax for URL and email.

Note: To include a bare URL or email without it being converted into a link,
wrap it in a code span:

```markdown
Not a clickable link: `https://www.example.com`
```

Note: The following scenario does not trigger this rule because it could be a
shortcut link:

```markdown
[https://www.example.com]
```

Note: The following syntax triggers this rule because the nested link could be
a shortcut link (which takes precedence):

```markdown
[text [shortcut] text](https://example.com)
```

To avoid this, escape both inner brackets:

```markdown
[link \[text\] link](https://example.com)
```

Rationale: Without angle brackets, a bare URL or email isn't converted into a
link by some Markdown parsers.
