How can I create custom colored icon font as Apple did for emoticons?
I'd also need a font making tool that imports .svg images.
For font making the common OS X tools are FontLab, FontForge, and Glyphs.
I understand the Color Emoji font uses png color bitmaps in two sizes in a proprietary “sbix” table, but have not yet seen info on how to make that table.
This link explains how to make a custom color font.
hope that helps!
