Anchors links to headers containing emojis are reported as invalid URLs #64
Description
Describe the bug
Material for MkDocs supports emojis
These can be placed in the body of text or in section headers, and have the form :emoji-identifier:.
This same syntax can also be used for custom icons:
Currently, anchor validation will fail for anchor links that are valid, but point to headers that contain an emoji.
