I have more details. In my case, I had in System settings -> Regional settings -> Formats:
Region: United States - American English (en_US)
Detailed settings enabled and time format set to Czech (cs_CZ). With this particular settings I can reproduce the problem plus I get the errors with locale. Once I switch this settings to "No change" are logout and log back in, Okular opens pdf files in a path with accents without a problem. I have confirmed it twice.
The locale outputs with the time set to "No change":
LANG=en_US.UTF-8
LANGUAGE=
LC_CTYPE="en_US.UTF-8"
LC_NUMERIC="en_US.UTF-8"
LC_TIME="en_US.UTF-8"
LC_COLLATE="en_US.UTF-8"
LC_MONETARY="en_US.UTF-8"
LC_MESSAGES="en_US.UTF-8"
LC_PAPER="en_US.UTF-8"
LC_NAME="en_US.UTF-8"
LC_ADDRESS="en_US.UTF-8"
LC_TELEPHONE="en_US.UTF-8"
LC_MEASUREMENT="en_US.UTF-8"
LC_IDENTIFICATION="en_US.UTF-8"
LC_ALL=
and this is the output of locale when I change time format to czech (with region en_US):
locale: Cannot set LC_ALL to default locale: No such file or directory
LANG=en_US.UTF-8
LANGUAGE=
LC_CTYPE="en_US.UTF-8"
LC_NUMERIC="en_US.UTF-8"
LC_TIME=cs_CZ.UTF-8
LC_COLLATE="en_US.UTF-8"
LC_MONETARY="en_US.UTF-8"
LC_MESSAGES="en_US.UTF-8"
LC_PAPER="en_US.UTF-8"
LC_NAME="en_US.UTF-8"
LC_ADDRESS="en_US.UTF-8"
LC_TELEPHONE="en_US.UTF-8"
LC_MEASUREMENT="en_US.UTF-8"
LC_IDENTIFICATION="en_US.UTF-8"
LC_ALL=

The above output indicates that something seems to be wrong with your
locale settings.
Can you please post the output of the command "locale"?
Does the problem go away if the respective locales are generated?
You can have them generated by running the command "dpkg-reconfigure"
(with root privileges) and selecting the corresponding locales. (The
above output suggests that those are "cs_CZ.UTF-8" and "en_US.UTF-8" in
your case.)
Regards,
Michael
