Discussion of article Real ❝Roman numbers❞ for Internet and office:
There is a unique UTF-8 code and Unicode for each Roman number.
For really important documents, a normal „V“, „I“ or „X“ is just recognized as a letter V, I, X, but never as a true Roman number. Two „i“ next to each other do not yield „ⅱ“, but only „i“ plus „i“.
It's actually a fallacy, whoever writes it as ordinary letters is cheating on himself.
After all, we do not write an „O“ and say: „Look, that's a laughing smiley.“ Or...?
