    @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%);
    }
    
    .QLineEdit:disabled
    {
        border-color: rgb(0,0,0,25%);
        background-color: rgb(255,255,255, 50%);
        color: rgb(0,0,0, 50%);
    }

    @Paul-Busovikov I would try without this style-sheet to be sure

        @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

                    And for what reason qt would not use fontconfig ?

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

                      @jsulm Thanks for answer. No, I didn't, but I have a log of building

                      So, as far as I understood it is the reason

                      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).
