Enable links for non-Arabic numbered pages in the Table of Contents

### Feature Request

### Problem / Opportunity

OpenLibrary offers a very helpful Table of Contents, that allows one to directly jump onto the relevant pages of an Archive.org item. It only works with Arabic numbered pages though, and some books use non-Arabic numbers for example for the front- or backmatter. The most common replacement for those cases are Roman numerals.

It is helpful if I can directly access pages in books with an elaborate front- or backmatter, which are the most likely to use Roman numerals for those pages.

When the Table of Content offers a link to sites that are numbered in non-Arabic numerals

### Proposal

There is a short amount of Roman numerals used for this regard, they should be treated as if their were an Arabic-numeral within the Table of Contents.

- Description of the [relevant Roman numerals](https://www.tuomas.salste.net/doc/roman/unicode.html)
- [OL7107765W](https://openlibrary.org/books/OL14291591M/Men_of_the_trees) Work with a clearly laid out Table of Content that uses Roman numerals which allows for easy testing
