It is not something left to the stylebook of newspapers (it is another matter though that some of them wouldn't know what it is!). I am very fastidious, personally, about getting the names and their spellings right. Yet, I followed the Deccan Herald style of spelling Srikanta Datta's surname as Wodeyar. It was only much later, when I signed the agreement with him on the book, that I found that he spells it as Wadiyar. When questioned, he said his predecessors did spell it as Wodeyar, but the new spelling was adopted by his immediate predecessors. So, the wrong spelling is indeed the right one!
