I have a problem on Roboto font where the Arabic language is not displayed correctly, on the fonts I'm not very prepared but I think it does not support Arabic unicode.
My project deals with a material theme for swing and therefore I would not change fonts for the Arabic language support so I thought that when the theme is loaded I check for a keyboard layaut and if that language is not supported by a robot then change font to loading, this is the only solution I could find but the solution does not work for devices without a keyboard.
Now I would like to ask you two questions:
---------- Problem Load Font to GraphicsEnvironment ------- I have rewritten fonts of different types and now through a method written by me I go to set the font according to the style and the support of the String but I get this problem when I go to render the look and feel

setting font on the button
Font font = MaterialFonts.getFont(button.getText(), "Black");
button.setFont (font);
problem rendering is enter image description here
'Roboto' is owned by Google... It doesn't support Arabic ... Google uses a fallback font named 'noto font' where 'roboto' isn't supported...
