A comparison of two PDF files: produced by LO PDF export (left) and PrimoPDF
(right) from the same ODT document

Problem description: 

Supplementary Multilingual Plane 1 characters are needed in my document to
render cuneiform glyphs. No problem to embed them in the ODT file using the
appropriate fonts (Aegean, Assurbanipal...) and the Insert special character
feature. When I export the file to PDF, however, the PDF file shows said
characters improperly, though the fonts appear to be embedded in the PDF
document.

Steps to reproduce:
1. Open a new LO Writer document
2. Insert some characters above 0x10000
3. Export to PDF
4. Read the PDF file with Acrobat Reader or equivalent

Current behavior:

The SMP1 characters from Aegean font appear as two boxed question marks.
Characters from Assurbanipal font appear as blanks. Nota: The problem dates
back from at least OO 2.4. It is still present in LO 3.5.

Expected behavior:

The SMP1 characters appear as they should...

Platform (if different from the browser): Windows XP

Browser: irrelevant

PDF Reader: Acrobat, Foxit
