Postgres hieroglyphs instead of cyrillic?

Question

PostgreSQL

I write the client's data to the database. The database is encoded in UTF-8, on the HTML pages the meta is UTF-8, but hieroglyphs are still written?

syuzyov did everything as you said, but it did not help, but still thank you very much.
Found this solution if anyone needs it:

try {
            customername = new String(request.getParameter("customername").getBytes("ISO-8859-1"), "UTF-8");
            customerlastname = new String(request.getParameter("customerlastname").getBytes("ISO-8859-1"),"UTF-8");
        } catch(Exception e) { //this generic but you can control another types of exception
            // look the origin of excption
        }

Somehow, there is not enough information at all .... Based on the results of telepathy, the following is recommended:
1. Check for the presence of the Russian locale and install if necessary. Example for debian:
sudo dpkg-reconfigure -plow locales
We find the locale ru_RU.UTF-8 in the list, mark and complete the configuration.
2. Next, when initializing the instance, you must specify encoding and locale. Example for pgpro10:
pg-setup initdb --encoding=UTF8 --locale=ru_RU.UTF-8
In the future, describe the environment right away, please.
