Relative distinguished names should accept unicode during CA creation.
I found improper behavior during creation of CA.
Data that was used to create CA:
emailAddressemail@example.com, ST=Malopołska, O=Idium Polska, L=Kraków, CN=Idium Polska Internal Certificate Authority, C=PL
After save configuration certificate didn't appeared in System -> Cert. Manager -> CAs, also none of the error code/info was returned (there was several attempts).
Problem was solved using ASCI letters in ST and L names, but both of that relative distinguished names should accept unicode characters.
