When possible, avoid asterisks.
Asterisks refer to some content on the bottom of a page or screen. Asterisks slow readers down. You’re interrupting their train of thought and asking them to hunt for secondary information.
If you need to cite legal content, you can use an asterisk as a footnote symbol if it’s the only footnote on the page. For more than one, use footnote numbers (this should be rare).
The asterisk goes before a dash, but after every other punctuation mark.
Do not put the asterisk in the middle of a sentence. Put it at the end. And never use multiple asterisks in one sentence.
