In any context I've seen, asterisks are for wrapping formatting and said formatting it to add emphasis. So being in the habit of typing `emphasised phrase`, for italics - regardless of whether the platform parses markdown/similar formatting, e.g. SMS.

To have an unclosed asterisk replacing characters in a word? I've only ever seen that as a way to bypass censorship. This spans communications from people currently in their 40s down to 20.
