Yup: that's why I put in quotes... I'm literally using "h?" as a Bash alias, as GP said.

It may be a bit weird to use a question mark as part of a Bash alias that said: sorry for the confusion!

For what it's worth, I like to use backticks in these situations (e.g. `h?`). I think it reduces ambiguity a bit.

I do this too although it can add ambiguity when writing about the shell!
