In Acrobat Pro, is it possible for letters input in a text field to be automatically made uppercase?

Further, is possible to restrict the text field to letters and hyphens?

You can do it using this code as the field's custom Keystroke script:

event.rc = /^[-a-z]*$/i.test(event.change);
event.value = event.value.toUpperCase();

Thank you! I had omitted that the field should be able to accept spaces as well, but then adding a space to the character class, as follows, sorted that out.

event.rc = /^[-a-z ]*$/i.test(event.change);
event.value = event.value.toUpperCase();

If you want to show uppercase as soon as you type it, replace:

event.value = event.value.toUpperCase();

with:

event.change = event.change.toUpperCase();

Only letters can be in upper case.
