           Summary: LibreOffice Draw / Adobe Acrobat interpret a PDF
                    differently (letters disappear in LibreOffice Draw)
           Product: LibreOffice
           Version: 5.0.6.3 release
          Hardware: All
                OS: All
            Status: UNCONFIRMED
          Severity: normal

Description:
Hello,

we use LibreOffice on an Ubuntu server to output PDF's for a
campus-management-system on our university. HISinOne is a rather common
software in Germany for universities to manage their students and staff.
Initially we used LibreOffice 4.4.6 and now also tried an update to 5.0.6.2 -
the Ubuntu version is Ubuntu 14.04.3 LTS. Sometimes those PDF's have to be
slightly adjusted or modified in our offices of academic affairs. The staff
there is using LibreOffice 5.1 on windows 7. 
I'll try to keep it short: our problem is that sometimes documents are missing
letters on some names depending on which program you use to open the pdf
document. 
I attach a document created on aforementioned Ubuntu servers on LibreOffice
5.0.6.2 - please try to open this document in 
a) LibreOffice Draw 
b) Adobe Acrobat (I used Reader DC 2017.09.20044 and Acrobat Pro XI 11.0.20)
c) optional Microsoft Word (I used 2013)

Depending on which program you use the name Stephan Wulff is written with 1 or
2 "f". So a whole letter disappears depending on the program - obviously this
is a real headscratcher for us. 

a) f
b) ff
c) f

As far as I tested so far every name ending on double - f has this issue but it
may not be confined to this character combination. I tested names with ff in
the middle of the surname without any issue.

The developer of the HISinOne software isnt able to provide additional support
in this matter and points to LibreOffice for further investigating, stating
that it has to be an issue with how LibreOffice is generating these PDF's. 
Please list any other speccs or testcase documents you might need and I will
try to provide them here.

Thanks
M.

Steps to Reproduce:
1. Pick a person that has a specific name pattern - surname ending on double f
2. Generate the specific report.
3. Open the PDF with LibreOffice Draw and Adobe Acrobat Reader etc

Actual Results:  
Surname is ending on one f

Expected Results:
Surname is ending on two f


Reproducible: Always

User Profile Reset: No
