Great! I got it working now. Thank you very much for your assistance Mr.
Soares.
The following lines did the job.
FontFactory.register("arialuni.ttf");
StyleSheet st = new StyleSheet();
st.loadTagStyle("body", "face", "arial unicode ms");
st.loadTagStyle("body", "encoding", "Identity-H");
st.loadTagStyle("body", "leading", "12,0");
However, this was just to test that I can produce these symbols and my
actual solution is a bit different and is specific to the Flying Saucer
project (which uses iText). I know this is not a Flying Saucer forum but I
think it might be useful to someone so here it goes:
I took two steps:
1). I added the following lines in the XHTML' s <head> tag:
<style type="text/css">
body{font-family: "Arial Unicode MS";}
</style>
2). I added the following lines (Flying Saucer specific) just before setting
the document to the renderer.
ITextFontResolver resolver = renderer.getFontResolver();
resolver.addFont(
"resources/arialuni.ttf", //this font displays math symbols
BaseFont.IDENTITY_H,
BaseFont.EMBEDDED);
Now, since I explicitly add a font in the FontResolver I would expect it to
work even without having to declare the font-family element in the XHTML.
But that don' t happen. You have to do both above steps. Well, of course I
hardly expect an answer to that here since it is a Flying Saucer matter.
Just in case anyone knows anything ...
