My 64-bit PC running Windows 7 Home Premium version has installed 3 major browsers, IE 11.0.9600.17914 (64-bit), Firefox (just updated to 43.0.3) and Chrome 47.0.2526.106 (64-bit). But all of them are incapable of showing some Unicode symbols, like this one 🤗. In Firefox, a rectangle containing the characters "01F" and "917" is shown instead, but in the other two browsers, only a rectangle will be displayed.
Even I go to this page http://graphemica.com/%F0%9F%A4%97, the same result occurs.
I have read the other post My Windows 7 has suddenly stopped displaying Unicode symbols, but I think my situation is a bit different. Those characters have never been able to show up. And for more information, there are some observations:
(1) Some symbols for Facebook emoticons can be shown correctly, such as these heart symbols. 💙💚💛💜💖
(2) I tried the solution suggested in https://www.facebook.com/help/community/question/?id=10202733484446539 (disabling hardware acceleration for Firefox), but it did not help.
(3) I tried the solution suggested in the accepted answer of My Windows 7 has suddenly stopped displaying Unicode symbols, but it did not work either.
(4) My Windows 7 is in Traditional Chinese, so perhaps the solutions in the US English version may or may not apply. But I'd still welcome and hope for suggestions in English Windows to see if they also apply to the Traditional Chinese version (and due to such hope, I did not specify the language in the question title).
Thank you in advance!
