6.2. Some characters are not displayed, or displayed incorrectly, or displayed as “#”.

This usually means the selected font doesn't have a glyph for the character.
Danke für die Antwort Thomas.

The standard text fonts supplied with Acrobat Reader have mostly glyphs for characters from the ISO Latin 1 character set. For a variety of reasons, even those are not completely guaranteed to work, for example you can't use the fi ligature from the standard serif font. Check the overview for the default PDF fonts.
If you use your own fonts, the font must have a glyph for the desired character. Furthermore the font must be available on the machine where the PDF is viewed or it must have been embedded in the PDF file. See embedding fonts.
For most symbols, it is better to select the symbol font explicitely, for example in order to get the symbol for the mathematical empty set, write:
<fo:inline font-family="Symbol">∅</fo:inline>
The "#" shows up if the selected font does not define a glyph for the required character, for example if you try:
<fo:inline font-family="Helvetica">∅</fo:inline>
