Probably you've installed the Noto collection on your Windows XP, or installed some software that added fonts to the system (pmossibly with updates to the Uniscribe library, suc has an old version of Office). Anyway I would no longer trust XP for doing correct rendering for many scripts, even with Uniscribe which is not needed for this simple character mapped in the BMP. Now minimal support in XP is essentially by third party software providers. Most have resigned, except Mozilla and some security suites that attempt to fill the gaps abandonned now by Microsoft (but still maintain it... because there are still various banks using it for example in their ATM: you know it when you frequently see the ATM rebooting of sometimes unusable as it has crashed with a "BSOD" displayed).
