[reportlab-users] FW: Adobe Reader - Outline Font.

We recently had to go through this ourselves. With latest reportlab we can 
use unicode encoding in that part of the pdf output and then PDF will respect the glyphs if the appropriate fonts are available to the reader. The fonts used are not a property of the document (I think), but of the viewing application. That's true for bookmarks at least. I believe the same is true for some of the annotations eg author etc etc.

The problem is that I cannot figure out exactly how this gets done in platypus/canvas land as the examples are all in rml eg

outlineAdd level="1">Ampersand (&amp;) and Japanese (またはご希望のホテルを1つ選択してください) Test</outlineAdd> <para>Check that the ampersand (&amp;) appears correctly in the outline/bookmark list.</para>

the above text in the example is good utf8 and when I view it I see japanese characters in the bookmarks.

I think it works like this:

1) the outline texts eventually end up using PDFString instances.
2) The PDFString instance checks to see if the text can be rendered using PDFDoc encoding. If yes that is used otherwise utf_16_be is output and then it's the viewer's responsibility to make the right glyph substitutions.

Robin,

Thanks for the reply. Seems tantalizingly close but I can't get it to work for me. I'm using Reportlab in the raw, not platypus but even ensuring that all my outline entries are UTF-8 encoded I still get garbage in Adobe Reader 7.

I attach a test program. Any advice?
