I wonder how whatsapp gives support for that. I could use emojis on iPhone because it is natively supported. I'm not developing for bb neither android but I need to help a coder with this stuff.
The bb guy told me that he can add a font as a project resource (ttf), but since emojis are colored graphics, I'm not sure if i can create a ttf. I do not know anything about fonts either.
As you can see, my unknowledge is huge on this. I just need some tips that point me to the right way to research.
Thanks!
On Android you can make a BitMap font with the tutorial i found here. Then you can embed all your Emoji into that font.
For making this on the BlackBerry you can use the FontFamily class.
Here is a tutorial that explains how this works.
Have fun! :-)
