iText-2.0.4.jar だけでも PDF は作成できるが、日本語フォントが描画できない。
iText, a JAVA-PDF library - ExtraJars1.0 にて iTextAsianCmaps.jar と iTextAsian.jar をダウンロードして実行時にクラスパスに含めるようにすれば日本語フォントが使える。

// iText Tutorial: Getting fonts
//
// > Fonts from jars (and font packs):
// > CID fonts are Postscript-based fonts which can support a large number of characters (65,536 max). The format is often used for CJK fonts (CJK = Chinese Japanese Korean). CID format makes it possible to change the character order (encoding) of a font through the use of character-to-glyph tables (CMaps) which are external to the font.
// > If you want to use CJK fonts in iText, you need an extra jar: iTextAsian.jar. If you want to be able to read the text you generated with iText using CJK fonts, you will also need to download and install a special font pack for Acrobat Reader (or maybe your Reader will ask you to install such a font pack upon opening a PDF file with CJK fonts). For the rest, creating a CJK font supported by the iTextAsian.jar is as easy as using any other font:
// >
// > BaseFont bfChinese = BaseFont.createFont("STSong-Light", "UniGB-UCS2-H", BaseFont.NOT_EMBEDDED);
// > Font FontChinese = new Font(bfChinese, 12, Font.NORMAL);
// > Paragraph p = new Paragraph(chinese, FontChinese);
// > document.add(p);
//
// > This is the list of fonts supported in the iTextAsian.jar:
// >
// > * Chinese Simplified:
// > STSong-Light and STSongStd-Light with the encodings UniGB-UCS2-H and UniGB-UCS2-V
// > * Chinese Traditional:
// > MHei-Medium, MSung-Light and MSungStd-Light with the encodings UniCNS-UCS2-H and UniCNS-UCS2-V
// > * Japanese:
// > HeiseiMin-W3, HeiseiKakuGo-W5 and KozMinPro-Regular with the encodings UniJIS-UCS2-H, UniJIS-UCS2-V, UniJIS-UCS2-HW-H and UniJIS-UCS2-HW-V
// > * Korean:
// > HYGoThic-Medium, HYSMyeongJo-Medium and HYSMyeongJoStd with the encodings UniKS-UCS2-H and UniKS-UCS2-V
//
// > CID fonts
// > But that's not all, there is also an extra jar iTextAsianCmaps.jar. It contains the cmaps for lots of other CID fonts. This is how you can use them:
// >
// > PdfEncodings.loadCmap(
// > "GBK2K-H",
// > PdfEncodings.CRLF_CID_NEWLINE); // needs to be done only once
// > byte text[] = my_GB_encoded_text;
// > String cid = PdfEncodings.convertCmap("GBK2K-H", text);
// > BaseFont bf = BaseFont.createFont("STSong-Light", "Identity-H", false);
// > Paragraph p = new Paragraph(cid, new Font(bf, 14));
// > document .add(p);
