Heh, yeah, I wondered what the German transcription was! Heck, English transcriptions aren't all that consistent either, especially as regards the vowels. I studied Arabic and Middle Eastern history back in university, and the bane of my life was looking up names online or in the index of a new book. "Okay, which of the ten possible spellings are we going with this time??" I don't at all envy you the multilingual translation back and forth. But in this case the consonants at least are pretty well fixed.
