 Set the `url` in front matter to override the entire path. Use this with either regular pages or section pages.
 
+{{% note %}}
+Hugo does not sanitize the `url` front matter field, allowing you to generate:
+
+- File paths that contain characters reserved by the operating system. For example, file paths on Windows may not contain any of these [reserved characters]. Hugo throws an error if a file path includes a character reserved by the current operating system.
+- URLs that contain disallowed characters. For example, the less than sign (`<`) is not allowed in a URL.
+
+[reserved characters]: https://learn.microsoft.com/en-us/windows/win32/fileio/naming-a-file#naming-conventions

+
+If you set both `slug` and `url` in front matter, the `url` value takes precedence.
+
+#### Include a colon
+
+{{< new-in 0.136.0 >}}
+
+If you need to include a colon in the  `url` front matter field, escape it with backslash characters. Use one backslash if you wrap the string within single quotes, or use two backslashes if you wrap the string within double quotes. With YAML front matter, use a single backslash if you omit quotation marks.
+
+For example, with this front matter:
+
+{{< code-toggle file=content/example.md fm=true >}}
+title: Example
+url: "my\\:example"
+{{< /code-toggle >}}
+
+The resulting URL will be:
+
+```text
+https://example.org/my:example/
+```
+
+As described above, this will fail on Windows because the colon (`:`) is a reserved character.

 ### Post-processing
 
 Hugo provides two mutually exclusive configuration options to alter URLs _after_ it renders a page.
