The place to find the answer is in the regex(7) manpage:

  https://manpages.debian.org/testing/manpages/regex.7.en.html

in which you'll find this sentence regarding bracket expressions:

  To include a literal '-', make it the first or last character,
  or the second endpoint of a range.

  (there's also more there about how to start a range with a `-`)

Cheers, Phil.
