Actually, I suspect (and can’t verify without seeing the PDF itself) that 
LibreOffice does NOT embed the fonts properly for use in form fields.

Subject: AW: [Podofo-users] Unicode in form fields

I use Arial, which i got into my linux environment via the 
I generate my forms using Libre Office, which doesn´t give me any options about
font embedding. I was hoping it embeds the whole font (and not just a subset)
automatically if (text) form fields are present. What I see inside this wiki 
is, that there are quite big differences between single fonts, maybe Arial is 
my best choice.

What font are you applying to the field?  If you want Unicode, you need to use 
a font that supports Unicode and is embedded appropriately.

Hi all,

when i write unicode strings into form fields (using podofo) only the Latin 
letters are shown,
Chinese and Cyrillic remain invisible when I look at it in a linux environment 
xpdf or evince. (The font is Arial, installed via the mscorefonts package.) 
it works fine with Adobe Reader in a windows environment. I found out, that
none of the base 14 fonts supports non Latin letters –  what’s the trick here? 
A PDF is able to
show Chinese or any other letters in a linux environment, but how can I get 
that to work with
form fields?
