In following this tutorial on Using Text as Container which essentially explains how to create a path from a letter, I've run into difficultly when trying to follow this on any letter that has a counter... like a, b, d, etc. When I right-click inside the original text, and convert it to a work path, and then I click inside the work path to begin typing with a new type tool... letters! lose their counters and the path is defined strictly by its outer edge. See the screenshot:
How can I adjust the work path so that the counter is preserved and you can see the hole in the letter a like you'd expect?
