The PDFzone.com has posted an article titled The Scoop on Font Embedding Restrictions. The article is of interest to Acrobat users that have been "struggling with font embedding in their PDFs." For example, it notes: "Among the changes introduced in v4.0, Adobe made Distiller aware of a special code bit that designates whether a font's license allows embedding. Suddenly certain fonts that embedded just fine with Distiller 3.02 can't be embedded."
