Anyone: can you tell me how to embed a small .eps dingbat into a nested style as a character style? No luck searching all day yesterday for the steps to take.
CMYK = a si gle color, or multi-colored?
Only if the entire thing has a single color: yeah, you can make a font of it. See http://forums.adobe.com/thread/1028609 -- the most recent One-Character demo can be downloaded from http://www.indiscripts.com/post/2013/05/indyfont-1-1-public-pro-releas e-and-users-guide
You can use your original InDesign drawing (NOT your exported eps!) but make sure to follow instructions, e.g., fill it with [Black].
This system does not work for multi-colored images. It is possible to create a font where each part should get its own color (you cannot 'save' colors in a font) but the demo is restricted to One Character Only.
