I agree, I see some type of backwards "deRomanization" used all the time by foreign students in the West. I've noticed it most prominently among the Arab and Persian students who end up on University computers without the ability to type in their native script. So they flub it with Roman characters and get by pretty much okay.

For Army Linguists that speak Korea, there's a similar system they use to write Hangul on an English keyboard. But it isn't phonetic.
