Source package: okular: /usr/bin/okular - following the guideline

1 ---- The release of Ubuntu you are using

lsb_release -rd:
 Description:	Ubuntu 20.04.5 LTS
 Release:	20.04

2 ---- The version of the package

apt-cache policy okular:
 Installed: 4:19.12.3-2ubuntu1

3 ---- What you expected to happen

Okular should display special language characters (in this case
hungarian)

4 ---- What happened instead

Some characters made no sense, replaced with symbols or special ASCII
characters.

Additional details:

- I pixelated parts of the document that affect my privacy.

- Someone suggested to apt-get install fonts-noto-core, but it is
already up to date.

- Someone also suggested to attempt using mupdf and it displayed the
characters properly.

- In Okular, while the PDF is opened I click on properties and click on
the Fonts tab and it has three columns:

Name: Arial-BoltMT (substituting with Liberation Sans Bold), ArialMT (substituting with DejaVu Sans
Type: CID TrueType, CID TrueType
File: /usr/share/fonts/truetype/liberation/LiberationSans-Bold.ttf, /usr/share/fonts/truetype/dejavu/DejaVuSans.ttf
