itext xmlworker不适用于自定义字体系列

Question

我的应用程序解析html并将内容放入pdf中，现在它需要支持多种字体，例如：缅甸和中国。

即使是单个字体系列，我也可以使用短语来做到这一点，但是不能使用html

工作代码

public class MyParsers
{
    public static readonly TokenListParser<PrjToken, string> Text = from text in Token.EqualTo(PrjToken.Text)
        select text.ToStringValue();

    public static readonly TokenListParser<PrjToken, Superpower.Model.Token<PrjToken>> Whitespace = from text in Token.EqualTo(PrjToken.WhiteSpace)
        select text;

    public static readonly TokenListParser<PrjToken, string> Title =
        from hash in Token.EqualTo(PrjToken.Hash)
        from text in Text
        from wh in Whitespace
        select text;

    public static readonly TokenListParser<PrjToken, string> Chapter =
        from chapterName in Text
        from wh in Whitespace.Optional()
        select chapterName;

    public static readonly TokenListParser<PrjToken, Book> Book =
        from title in Title
        from chapters in Chapter.Many()
        select new Book(title, chapters);

    public static readonly TokenListParser<PrjToken, Library> Library =
        from books in Book.Many()
        select new Library(books);
}

尝试过XMLWorker，但是没有用：

Document document = new Document();
PdfWriter.getInstance(document, new FileOutputStream("/home/a2.pdf"));
Font font = FontFactory.getFont("KozMinPro-Regular", "UniJIS-UCS2-H", false);
Font font1 = FontFactory.getFont("/home/mm3.ttf", BaseFont.IDENTITY_H, false);
FontSelector fs = new FontSelector();
fs.addFont(font);
fs.addFont(font1);
Phrase phrase = fs.process("長");
phrase.add(fs.process("၀န္ထမ္းလစလႊာ( လ )"));
phrase.add(fs.process("123aab"));
document.open();
document.add(phrase);
document.close();
