Thank you in advance for the info. Now I understand that's why :)
rupiah (Rp), the currency of Indonesia. I haven't seen in the range of Unicode currency. So far I do encoding into F6DD. ... then automate to the OTF features, ligature. It has been the topic of discussion for some time in typophile here:http://typophile.com/node/16012
The type designers (even into some old font of Linotype) thought it was the same as the rupee (India).
But think of rupiah symbol consists of two real characters, and I think this deserves a place in one of the boxes code :)
If all currencies are ever known get a position in Unicode, it will change the writing of OTF's script associated with currency. Is my opinion true?
