Original docx file

This has originally been posted in the forum, see here:

I am running MSOffice 2007 on Wine 2.4 on Arch. It is running very well and I
am using it to prepare PDF files from various office files in the background.
The PDF files look very good and are searchable. However, they contain text,
which is malformed. This depends on the font encoding, I suppose.

As a test setup I copied my Fonts directory from my windows machine to the
respectuive wine prefeix/drive_c/windows/Fonts and also installed them in the
truetype fonts directory on the linux machine (/usr/share/fonts/TTF + fc-cache
and fc-cache-32). So the PDF printing picks up all necessary fonts.

Printing is done via cups-pdf. Currently at 3.0.1, but I have tried several
versions starting from 2.6 inclduding and not indcluding several patches found
on the internet:

https://github.com/alexivkin/CUPS-PDF-to-PDF
http://www.linuxquestions.org/questions ... 175440557/
https://launchpadlibrarian.net/15378121 ... port.patch

It seems that the cups-pdf driver is not the culprit here, as the result is
always the same.

My test.docx is attached and contains two lines ('test') the first one in
Calibri, the second one in Arial. When I print this docx with wine 2.4, Word
2007 and cups-pdf, a pdf file is created, which looks fine (s. attached), but
when I copy and paste the text, I get:

'[garbled text]
test'

So apparently, the Calibri-font part is somehow problematic.

pdffonts test_wine.pdf
OQHKQC+ArialMT Type 1C WinAnsi yes yes no 10 0
YIGKZZ+Calibri Type 1C Custom yes yes no 8 0

I know I can directly save the docx as a pdf in word and I can also automate
this via a makro, but I also would like to print from Outlook, which is not as
easy to automate as Word via makros, but easily prints via tjhe /p command line
switch.

When I directly save the docx as pdf, I get:

'Test
test'

pdffonts test_wine_savepdf.pdf
ABCDEE+Calibri TrueType WinAnsi yes yes no 5 0
Arial TrueType WinAnsi no no no 7 0

The difference is that the Calibri font is encoded WinAnsi and not custom.

I checked whether the cups-pdf driver might be the culprit by opening and
printing the test.docx file with a native copy of libreoffice and I get:

'Test
test'

pdffonts test_lo.pdf
BAAAAA+Calibri TrueType WinAnsi yes yes yes 14 0
CAAAAA+ArialMT TrueType WinAnsi yes yes yes 9 0

So, basically, both the cups-pdf driver and wine/word are able to encode
WinAnsi, but printing via Word apparently forces the cups-pdf driver to include
custom-encoded font-subsets. I somewhere read that ghostscript cannot do
anything related to reencoding fonts, so I assume that there is something wrong
before cups-pdf starts.

Further observations:

If I use the 'print to file' option in Word (wine) and Word (Windows machine)
to produce a PS file, further processing with ghostscript produces a PDF with
garbled copied text and Type 1C, Custom encoding Calibri, whilst the same
command produces a PDF with copiable text and TrueType, WinAnsi encoding
Calibri.
