About the missing Emoji, I think I've figured it out. My MacBook laptop is 3-4yrs old now. The version of OsX it is running is outdated. Until now I've never run across a problem, but this looks like the 1st sign of things like the Emoji which are beyond my outdated OS.
Although Apple has repeatedly offered me free upgrades, to date I've not accepted any of them. My reason? Mostly Steve Jobs or rather the lack thereof. My OS officially became obsolete, prompting Apple to offer me updates to newer versions, about the same time that Steve Jobs left the company. I liked the innovative atmosphere he brought to Apple. His death left me concerned about whether subsequent products would continue to have the same qualities. I've held off on upgrades for fear of loosing the features I love about my Mac and, instead, ending up with something more like Windows.
When El Capitan came out, I gave some thought to upgrading, but decided against it after reading that while some people love it many others are having major problems with it, and the dividing line between the happy people and the sad people seems to be memory. It needs a LOT of memory, and although it claims to work on the amount of memory I have, based on user reviews it only seems to work well on computers with more memory. Plus, and I'm really glad I read this before upgrading, once you upgrade to El Capitan, you can't easily remove the upgrade and go back to your old version. Some of your files, photos, etc get updated to fit the new OS, and can't be accessed again if you drop back to a lower version. Argh!
So this is why I'm still using the older OS and apparently why I'm not able to view those Emoji characters.
Rosie, what kind of device are you using? Just curious.
