Cyrillic diaplay on entered data

We are using Cyrillic Characters in Dolibarr and have a problem with the display. Once the data is entered and saved it only displays as ???. For PDF we figured out that DejaVuSans as Font is the solution.

Any help much appreciated!

Hello
I made this for a russian customer within ultimatepdf. You can choise DejaVuSans font within your models.

Thanks, yes fir PDF the solution was easy. Any idea how to enable the display of cyrillic on dolibarr itself. As the screenshot above shows any entered text displays as ???

Sorry attachment fails. Can you resubmit it again ?
Can you provide an url and temporary account on your instance to check ?
What is your database codepage ?
What is your language ?

attached the resubmitted snapshot.

you want me to generate temporary user for you? what kind of permissions do you need to check the necessary?

Database codepage: Database charset to store data utf8
Database charset to sort data utf8_general_ci

Language: Bulgarian (cyrillic characters), switching language in the database from english to bulgarien did not help so far. Menu and everything else is well displayed in Cyrillic characters, only our inputs do not display.

Solution to above was changing the encoding in the config file from latin1 to utf8.
