    tdf#113448 don't export any font for radio buttons
    
    Don't let only color value in m_aDAString since it'll go here:
            if( !rWidget.m_aDAString.isEmpty() )
            {
                if( !rWidget.m_aDRDict.isEmpty() )
                {
                    aLine.append( "/DR<<" );
                    aLine.append( rWidget.m_aDRDict );
                    aLine.append( ">>\n" );
                }
                else
                {
                    aLine.append( "/DR<</Font<<" );
                    appendBuildinFontsToDict( aLine );
                    aLine.append( ">>>>\n" );
                }
                aLine.append( "/DA" );
                appendLiteralStringEncrypt( rWidget.m_aDAString, rWidget.m_nObject, aLine );
                aLine.append( "\n" );
                if( rWidget.m_nTextStyle & DrawTextFlags::Center )
                    aLine.append( "/Q 1\n" );
                else if( rWidget.m_nTextStyle & DrawTextFlags::Right )
                    aLine.append( "/Q 2\n" );
            }
    
    But if we shouldn't have /DR at all since we don't want fonts for radiobutton, it also means
    we don't want /DA too.
    Indeed at the end of 12.7.3.3 https://www.adobe.com/content/dam/acom/en/devnet/pdf/pdfs/PDF32000_2008.pdf:
    The default appearance string (DA) contains any graphics state or text state operators needed to establish the
    graphics state parameters, such as text size and colour, for displaying the field’s variable text. Only operators
    that are allowed within text objects shall occur in this string (see Figure 9). At a minimum, the string shall
    include a Tf (text font) operator along with its two operands, font and size. The specified font value shall match
    a resource name in the Font entry of the default resource dictionary (referenced from the DR entry of the
    interactive form dictionary; see Table 218).
