It seems that certain (not all) emoticons are missing in my Windows 7 Ultimate x64 SP1 installation. The table of emoticons from the Wikipedia article looks as follows on my system:
Windows Update KB2729094 which should address this issue is installed.
What can I do to get the missing emoticons? Deciphering them in incoming E-Mails is getting old... :-)
I did find the solution for Firefox:
In about:config, set gfx.font_rendering.fallback.always_use_cmaps to true (default value is false).
With that, only 5 of the emoticons in the Wikipedia article remain broken (see screenshot below). That's probably as good as it will get in Windows 7 with Firefox.
Internet Explorer 11 and Chrome both show 17 broken characters.
