/**
 * Fonts that are not embedded: the twelve text faces of the core fonts, and
 * Chinese, Japanese and Korean in the CJK fonts.
 * <p>
 * The PDF names each font and the viewer supplies it, so the document carries
 * no glyphs: it is a few kilobytes, where an embedded CJK font adds hundreds,
 * and it is written in a moment. The cost: the text takes the shapes of the
 * font the viewer has, so it does not look the same everywhere; the core fonts
 * draw only the characters of Western European languages; the CJK fonts need
 * the Adobe Asian font pack, and draw Latin letters and spaces full width; and
 * a document with a font that is not embedded cannot be PDF/A or PDF/UA. To
 * carry the glyphs with the document, use an embedded font, as Example_02 and
 * Example_03 do.
