True written language app for the monolingual masses

[The Alterother] is fully fluent in only one language: English (two, I suppose, if you consider American and Queen's separate). I'm partially fluent in German, Franglaise, and html. I can find the bathroom and/or pick a fight in most romance languages. All of these languages share the same character set (except for the extra letters in German, which are self-explanatory).

Let's say I'd like to translate a written word or phrase from Arabic or Korean using an iPad or another device equipped with a touch- screen keyboard. This app would switch the character set on my keyboard to that of the selected 'from' language, allowing me to hunt and peck until I can reconstruct the word I'm looking at, be it on a street sign in Cambodia, a restaraunt menu in Midtown Manhattan, or the tattoo on some hipster's shoulder.

I've hunted the 'bakery and the web, and the only things I can find that do this are dedicated translation devices, usually ones with physical keyboards that only work with one language. For the purpose of satisfying my abundant yet idle curiousity, I can no more carry around a satchel full of these than a library of ___- to -___ dictionaries. I want an app, dammit!

PS: I couldn't work any mention of rhinoceroses into this idea. My apologies to those who were expecting it. I'll try harder next time.
