I don't know of a font that does Arabic->Roman numeral translation as
glyph substitution while preserving the original Arabic code points.  I'm
considering building an Arabic->Roman translation as a "Stylistic Set"
feature (ss01, ss02, etc.) in one of my own projects, but my current plan
is to make it translate the code points too, so if you write "3" with the
feature turned on, it appears as "iii" and then if you copy and paste
that, you end up pasting "iii".  It sounds like that's not what you want.
