NOTE: This bug report is for Confluence Server. Using Confluence Cloud? See the corresponding bug report.
Summary of Bug
When a page is exported as PDF, special characters like Ω and µ are omitted.
How to reproduce
- Create a page, and include special characters like Ω
- Save the page, and then 'Export as PDF'
- In the PDF file, the 'Ω' character is completely missing
Findings
I have tried this in Confluence 4.0.3, 4.0, 3.5.9, 3.4.9, 3.3.3, 3.1.2 and 3.0.0_01. All of these versions suffer from the same problem. Have tried disabling and re-enabling the PDF Export plugin, then restart Confluence instance, but problem persists.
This is how it looks like in the editor :
This is what happens after it is exported as PDF :
Workaround
Upload a font that contains these symbols to Confluence, as detailed in CONF-25887.

[CONFSERVER-23778] PDF export omits special characters like µ and Ω
Um, this shouldn't be low priority. These are basic text characters. Could you please raise the priority of this and/or CONF-30779 (which doesn't even seem to have a priority since it's just a "Suggestion")
For those who upload a new font and still see problems (particularly with mathematical symbols), please try the font in CONF-25887.
Hi Everyone.
Given that the resolution to this issue is to provide a new font for PDF rendering in Confluence I am going to resolve this issue as duplicated by CONF-30779.

added a comment - Hello,
tried the documentation's resolution. Sadly no improvements. Special characters are still lost.
I took verdana.ttf as font.
Do I need to fix something with the pdf's css?
Cheers

Cheers We suspect this is actually related to a font problem and not a Confluence code problem, for instance I was able to export a PDF with those characters with no problem.
Can you try the resolution in this document and let us know if it works for you?

added a comment - I want to confirm these bugs in Confluence 4.3.5 too.
There are even more special characters like arrows which aren't rendered in PDF exports.

There are even more special characters like arrows which aren't rendered in PDF exports. It's possible that you're experiencing a font problem. Please try the solution in this document and let us know if this resolves your issue:

Further testing shows that Chinese characters are also omitted in PDF exports.

added a comment - Could this be a font issue as supposed here ?
This bug shouldn't be labelled "resolved".
There are situations/ C.I. requirements where you have to use one specific font for your documents. Doing that just to find out that the finished PDF document arbitrarily omits characters, distorts information and changes values like "100 µs" to "100 s" (which actually means that the information is falsified by a factor of one million!) is completely unacceptable.
The result of this?
Imagine browsing through numerous PDF documents to search for all kinds of special characters that might or might not be there. On top of that you have characters like µ that exist in two versions, one of which works in the export, the other one not!
I could go and on.
