The "woman" manual viewing utility is stripping dashes from ranges. Is
that a known bug?

I am viewing crontab(5) with `woman` and I notices that the dashes in
number ranges are stripped out. My Emacs buiild is 27.1

This is a sample of what is displayed

          field          allowed values
          -----          --------------
          minute         059
          hour           023
          day of month   131
          month          112 (or names, see below)
          day of week    07 (0 or 7 is Sun, or use names)

instead of

          field          allowed values
          -----          --------------
          minute         0-59
          hour           0-23
          day of month   1-31
          month          1-12 (or names, see below)
          day of week    0-7 (0 or 7 is Sun, or use names)


Is it a known thing, or could it just be bug in my system?

so you can't run cron jobs on leap seconds?

My disappointment is immeasurable and my day is ruined.

This does not happen on my system.

        The time and date fields are:

                field          allowed values
                -----          --------------
                minute         0-59
                hour           0-23
                day of month   1-31
                month          1-12 (or names, see below)
                day of week    0-7 (0 or 7 is Sunday, or use names)

        A field may contain an asterisk (*), which always stands for
        "first-last".

Confirm for Emacs 29.0.50 master `0a8e88fd8`.

The `*WoMan-Log*` buffer says

    **  Special character (en not interpolated!

In the source of `crontab` man

    minute      0\(en59

If woman is stripping that couldn't be a bug.

I suggest to check your fonts. Maybe it's trying to display the dash
as an Unicode one.

I can reproduce it on Emacs 28.2, both on a vanilla and a Doom
installation.

How do I go about this?

My font is DejaVu Sans Mono.

I get the problem in terminal Emacs as well

Is there a link to this bug or commit?

I didn't report a bug.
But, I think, the source of the issue was [`woman-special-characters`]
(https://git.savannah.gnu.org/cgit/emacs.git/tree/lisp/woman.el#n2871)
lacking mapping.

I take it that I can fix this for myself if I know what lines to add
or change in this file?
