It's common to write foreign names in a slightly modified way matching the language used. This can be done to avoid uncommon character sets (you're going to write Moscow, not Москва), or simply because it sounds better in the sentence / people know how to read it (Warsaw, not Warszawa). Same happens with names.
Your comment sounds like there's something strange about adapting the name to the language currently used.

English continues to be used today, in combination with Hindi (at the central level and in some states) and other languages (at the state level).
