The file contains russian and english text in the "family name(surename)" field.

Hello,
+I can confirm this behavior with poppler-utils (0.16.3-1)  and okular  4:4.4.5-2
For some Esperanto's caractere, and Chinese, Russian , etc. (but not for š ß þúùûü ý ÿ ž by example :/)

+Okular's sample output:
[..]
Annotation Widget not supported. 
Annotation Widget not supported. 
warning: layoutText: cannot convert U+041F
warning: layoutText: cannot convert U+0440
warning: layoutText: cannot convert U+0438
[..]

+Please, have a look to the concerned section of a pdf  file : 
(the interesting sentence is "Les dév de Poppler sont fabuleux !!!! FIN Привет FIN")

+ You could also notice that when you fill a form and you save it, and next, re-fill the form and you save it.  
All the history of revisions is available in pdf content ! 
I supposed that it's a bug of the form's edition   (okular is responsible ?) ? 

Best regards

Hi. I'm also hit by this bug and I'd like to fix it.

I see the issue is the following:
- unicode-to-charcode map is not loaded from an external font, even when there's cmap table in it;
- form text conversion by the ccToUnicode->mapToCharCode fails for the symbols with codes > 255 in AnnotWidget::layoutText;

Do I understand it right that provision of GfxFont subclass that can load an appropriate cmap table and initialize its CharCodeToUnicode instance with it is the right way to deal with this bug, or is there a better way?

Any news?

Sorry for impropriety, but is there any progress on this? 
Maybe some rough assumption about when libreoffice will be able to embed unicode fonts in forms?

All the same with poppler 0.16.7-1.
If I have some free time the next week, I'll dive into sources and try to  understand(and probably fix) the problem.

I need this solution also as well as my friends. The bug prevents from using okular (and Linux generally) huge amount of users.

Don't play with the priority.

The problem IS ACTUAL!
Any progress?

Also hit this bug.

Confirms bug.

Isn't this a duplicate of https://bugs.freedesktop.org/show_bug.cgi?id=17913 ?

For solve this issue can we use as workaround - system-default character font for symbols that displays with "warning: layoutText: cannot convert"? This is better that display empty space instead of character.
