Indo-european in a sentence as a noun

Again I cannot really say anything for Urdu, but knowing it is not arabic but afaik a language of the indo-european family I wonder if there are more reasons to use the lating alphabet than just availability of nataliq fonts and rendering engines. As a side note I would add a few observations relating to the cultural/heritage aspects.
