>
> Hello,
>
> last week, one user of my Java-written jfig graphics editor asked
> me about a pure-Java PDF export option and pointed me to the itext
> project. I just hacked a simple class that interfaces jfig to itext
> via the PDFGraphics2D approach - and basic rendering including all
> line attributes and embedded images works pretty well.
>
> However, there is one important problem. When exporting files that
> contain Unicode characters outside the standard (0x00 .. 0xff) range,
> namely the math symbols included in the JDKs lucida.ttf files, those
> characters are lost. This is a little annoying, as the support of
> math formulae would be the main advantage of the pure-Java approach
> over the existing fig2dev-ghostscript toolchain.

> Many of the itext tutorial examples demonstrate how easy it is to embed
> Unicode characters (outside the 00 .. 0xFF range) into the PDF documents,
> but none of them seem to use PDFGraphics2D or the Java way of font
> handling ("SansSerif", "MonoSpaced", ...), which I need to re-use my
> existing object rendering code.

> Due to the way jfig currently formats equations - aligning boxes of single

> Therefore, I have the following questions:
>
> * How do I convince itext to not replace the Lucida font(s) with the
> Postscript/PDF equivalents?
>
Register the font in DefaultFontMapper.
> * How do I get the PDFGraphics2D and/or DefaultFontMapper to embed
> all required Unicode characters into the PDF file?
>
Set the encoding to Identity-H also in DefaultFontMapper. See the
example free_chart.java in itextpdf.sf.net.
> * I am aware of the licensing issues around the JDK Lucida fonts.
> Do you know of any other truetype fonts that (1) are free, (2) can

Arial Unicode, Lucida Sans Unicode. You can get them from
http://shlimazl.nm.ru/rus/mixfonts.htm. I don't know how legal it is to use
them outside windows.
