Description Alexander Potashev 2009-05-19 13:14:18 UTC 
Version:           0.8.80 (using KDE 4.2.85)
OS:                Linux
Installed from:    Gentoo Packages

1. open PDF with forms
2. click "show forms"
3. write text in Russian into a text input box (you can see the text in it)
4. click "hide forms"

Text in Japanese has the same issue, but English text, however, works.
This might be just a unsuitable font, but I don't know how to change the font.

Could you provide a sample document showing the issue?
Also, which version of the poppler library do you have?

You can, for example, enter "Привет!" ("Hi!")

I had 0.10.6, now I updated to 0.10.7, but the problem still exists.

Poppler problem indeed. When running either Okular or Evince from command-line, it gives
warning: layoutText: cannot convert U+041F
warning: layoutText: cannot convert U+0440
warning: layoutText: cannot convert U+0438
warning: layoutText: cannot convert U+0432
warning: layoutText: cannot convert U+0435
warning: layoutText: cannot convert U+0442
which makes me think there's a bug in Poppler wrt handling of unicode text when drawing PDF forms.

Cold you please report the problem to the Poppler's bug tracking system at https://bugs.freedesktop.org, "poppler" product? This way the problem can be analyzed by the Poppler developers (and possibly fixed).

Thanks!

A quick note for all the people who are landing to this bug: the status of this bug is unlikely to change, as the issue comes from the underlying library used for PDF (poppler), as already stated. If you want to be updated on this issue, please check the upstream bug ("See also" field).
As a personal suggestion, adding other comments like "any updates" is not going to help, neither is going to have it fixed faster (but only to piss off developers). If it has not been yet fixed it, this probably means that the fix is not easy. Patches are always welcome.

Can't add it to 'See also', so leaving new upstream issue URL as a comment: https://gitlab.freedesktop.org/poppler/poppler/issues/230
Comment 8 Luigi Toscano 2019-02-28 10:11:03 UTC 
'See also' now also supports freedesktop issue URLs (thanks to sysadmins)
