Roman numerals (was Re: How to write Armenian ligatures?)

Justin Kerk quoted from the standard,

Based on the text quoted from the standard, it appears
that CJK users are welcome to use Roman numerals, but
Latin script users are discouraged from doing so.

There are many things I like about the Unicode Standard,
but assigning a character and then telling people they
mustn't use it isn't one of them.
