converting XFA PDFs using ghostscript - problem with encoding?

Dear ghostscript developers and users,

for some time, we're struggling with PDF files produced by SAP based
portal. Problem of those is, that they contain XFA-based forms and
no linux reader other then adobe reader can correctly display them. Since
it got discontinued years ago, I'm trying to find solution for something
poppler-based, especially evince.

I got good tip from kind soul that I can use ghostscript to render XFA
PDF into normal one using something like

ps2pdf -dShowAcroForm odmeny.pdf odmeny2.pdf

then indeed I can view previously missing content from XFA
data.

the only remaining problem I need to solve now is that converted
content seems to have mangled encoding or something else is wrong
and accented characters like š just don't display correctly.

pdffonts shows that source pdf contains 3 fonts:

name                                 type              encoding         emb sub uni object ID
------------------------------------ ----------------- ---------------- --- --- --- ---------
RQUYXD+MyriadPro-Regular             CID Type 0C       Identity-H       yes yes yes     21  0
MyriadPro-Regular                    Type 1            WinAnsi          no  no  no      34  0
RQUYXD+ArialMT                       CID TrueType      Identity-H       yes yes yes      6  0


by checking source pdf and the text which gets converted (incorrectly) the problematic
part is the one with ArialMT, which seems to be embedded...

Would somebody have a tip on how could I fix that last remaining issue?

any help would be greatly appreciated

with best regards

nik
