Yikes. I'm too deep into this -- I knew exactly where to go for the answer. I was about to write that I did not believe ECUSA's 1979 "BCP" (to use a Dr. Peter Toon-ism) was in use anywhere else, but then a little question arose.
I will note that this page is not complete. The image to the right is a link to the Book of Common Prayer in Farsi (Iran).
Here are other translations and their origins. (I cannot read them, but I think the left-hand image is Arabic and for reasons I can't explain something about the characters makes me think the one on the right is Japanese, though it's more likely Taiwanese Chinese.)
And here are C of E and ECUSA BCPs.
I'm Catholic myself, but I have a great affection for the traditional Prayer Book -- through C.S. Lewis, mainly, though I bought one in graduate school, primarily for a paper I was doing on T.S. Eliot.
I have followed the depredations (so like those in our own liturgy) with sadness!
