Changing font family to Tahoma

[rasheed]

Arabic text doesn't seem readable at the editor, can you change the following fonts to Tahoma?

body {
  font-family: Tahoma,"Times New Roman","Bitstream Charter",Times,serif;
  font-size: 14px;
}

at: wp-includes/js/tinymce/skins/wordpress/wp-content.css

and,

.wp-editor-area {
  font-family: Tahoma,Monaco,monospace;
  font-size: 14px;
}

at: wp-includes/css/editor-rtl.min.css
