As for smart fonts, I'm not sure I understand these correctly. I personally think it would be interesting to see language-sensitive fonts that treate Arabic and Persian numbers as different shapes for the same numbers; this could be important in preventing security breaches. But this is not how it's done. That said, I don't think everything can be handled by smart fonts.And in fact, had we relied on smart fonts to display one single set of numbers as either Persian or Arabic, we would have had to wait for the apps/smart fonts to come along. (Perhaps then someone like yourself would haved created all the needed fonts.)Then there are proposals for new unicode characters, for example the Urdu jazm (syllable coda, termination of a syllable); to display these currently correctly relies on language-specific styling and some fonts can do it and some cannot; perhaps I should have favored the encoding of a new character here but for security reasons I decided the current characters we had should be sufficient.
As for transliterating, then making a smart font, again I am unsure I understand smart fonts here, can all languages can be transliterated character-for-character? Arabic, for example, has two aliphs, dagger aliph and standard aliph. The phonetic transliteration into Latin, for both, is identical.
Nevertheless, transliterations, where the user selects from several characters to get the right character, can be very helpful and save tons of downloading of whole character sets in the case of languages such as Chinese that have a huge inventory (the code charts even do not download onto my mini at all). Character pickers can work this way, letting the user input a Romanized character (which is just fine for users who know the Latin alphabet and many do; I am, of course, unfamiliar enough with smart fonts as to be unsure as to whether these would handle the dagger and standard aliph properly. Would they handle this properly?).
(Sorry that I always use Arabic as my example; I know Arabic somewhat; and a few words/phrases of Persian; I have zero familiarity with most other Asian languages. And P.S. I don't make money from participating in the list though it may help me at some point to "pad my resume" -- that is to add a comment that I participate in lists; in any case, I do think it is great IMO that the web has supporters among/technical input from both individuals and commercial users as well as places like the Library of Congress.)
Best,
