    Also it isn't matter what font I choose.
    I took "Ubuntu" font and there were rectangles which look as undefined characters looks like
    U+25cf is displayed like that, everywhere ( label lineEdit etc. ) during I build my project in sandbox

      Weird! Sorry, but I ran out of ideas how to help here :-(

      I've looked through known Qt bugs, the only one remotely related is https://bugreports.qt.io/browse/QTBUG-23626?jql=text ~ "echoMode" but I don't think that's it.

        @Paul-Busovikov Are you changing anything related to fonts and style in your app? For example style-sheets?

          @jsulm yes, I have style-sheet for those widgets, but I've tried same sheets for the build where I have no problem

          that is the one of them, can it spoil something?

          .QLineEdit
          {
              min-height: 32px;
              qtproperty-hsizetype="Maximum";
              border-radius: 2px;
              border-style: solid;
              border-width: 1px;
              border-color: rgb(0,0,0,25%);
              margin-top: 4px;
              margin-bottom: 4px;
          }
          
          .QLineEdit::focus
          {
              border-color: rgb(0,147,196, 85%);
          }
          
          .QLineEdit:hover
          {
              border-color: rgb(0,0,0,40%);
          }

                @Paul-Busovikov When you start your app do you see any warnings/errors? You build your app on Debian but execute on Mint: did you deploy it (http://doc.qt.io/qt-5/linux-deployment.html)? Could be that it doesn't find the font and falls back to some other font.

                  @jsulm it does find the font, I saw the differences and features of particular fonts
                  I deploy it by coping qt libraries (which were used during the compilation in sandbox) and their dependencies and qtplugins and fonts into a path available for app
                  During the work there are no warnings or errors

                  Can it be some codec problem? I suppose it is UTF-8 in both cases. How can I check it?
                  Just printed 10000 characters to see how it looks like

                  QString s;
                  for ( int i = 1; i < 10000; ++i )
                  {
                       s.append( QChar(i) );
                  }
                  ui->textEdit->setText(s);
                  

                  There are 2 variants0_1501070905064_55.png

                    @Paul-Busovikov In the second output you can see that much less characters can be properly shown. To me it really looks like a font issue. Internally QString uses UTF-16.

                      @jsulm you are right

                      QFontDatabase().families().join(" | ")
                      

                      gave me some clue
                      The first app returned whole list of families and the second one returned the only one which I deployed

                      QFontDatabase::addApplicationFont( "fontDir/myFont.ttf" );
                      

                      but I don't understand where both apps are looking for fonts
                      how can I force the app to look for in /usr/local/fonts not only in my deployed font directory?

                        And for what reason qt would not use fontconfig ?

                          I don't figure out why fontconfig don't work
                          But I have solved this particular issue by adding path to free fonts in QT_QPA_FONTDIR

                            For example because it was built without fontconfig support. Did you build Qt by yourself?

                                Also for the people who got similar issue there is the way to change password character by style-sheet

                                lineedit-password-character: 42;

                                @Paul-Busovikov If you would like to know why fontconfig was built execute configure again with additional -v parameter and check the output. I guess you're missing fontconfig header files (dev package).
