Turn this into a regular expression in which each character is optional
a?e?f?m?r?r?
Sort the characters in the short string into code point order, and test
whether the result matches this regular expression.
I can't see what you're getting at, but I can't convert it into a
working example:
matches('hello', 'a?e?f?m?r?r?')"
returns true, which suggests the regex needs work... but I don't know
regex's well enough to correct it.
