If you are more familiar with working in Illustrator, it can be an attractive choice. But there are quite a few drawbacks compared to working directly in a font editor:
- Conversion of outlines from Illustrator's floating point coordinated to integer values in a font editor (which are required by standard font formats) requires careful inspection for rounding errors.
- More steps involved, compared to drawing directly in a font editor.
- No way to effectively work on spacing in Illustrator in a way that will carry over to the font editor.
- Paths from Illustrator often need cleaning up in the font editor.
In general, it's faster and more efficient to work on a font directly in a font editor. That's what they were made for, whereas Illustrator was not.
If you do prefer working in Illustrator anyway, ScanFont provides a good, fast way to get the outlines into FontLab from Illustrator, although it's still more work than working in a font editor from the start.
(This is coming from someone who used to do his drawing in Illustrator.)
I think just letting people work out what suits them is the best thing.
I too have used Freehand, CorelDraw and Illustrator. (Freehand was ahead of it's time)
I always believe that when a program crosses over without two much loss, do it.
I come from the Toy Industry and you cannot design wildly original fresh Graphics in Quark or InDesign ....or a Font Editor ;-)
Likewise with some Unique Type Design. You cannot always quickly create original Fonts in FontLab or Fontographer. These programs are too unforgiving. You can't cut, overlay, swap, add, remove, try multiple images next to each other, on top of each other, move art/images around, off pasteboards, or work as quick on many glyphs as you can in a Vector Program like Coreldraw or Illustrator. You guys forget that while the impression is that while Font Editors might be the end result of precision, the Vector based Programs can be the source of freedom, creativity and freshness.
Some people use a pencil and paper. Some people like the speed and fluidity of Illustrator or Coreldraw to get a start on the final look of a typeface.
Each to their own. (But if you want to produce a boring Travel Brochure use Quark/InDesign...DON'T do Graphics IN IT...do page layout instead!)
If you want to set your creativity free, don't go near a Font Editor first!
