Icons

• make a font at http://fontello.com/ or something and download it

• from font file (for example .ttf) create vfs_fonts.js file (see how to use custom fonts)

• define font in js (just defining normal might be enough):

  pdfMake.fonts = {
      Fontello: {
          normal: 'fontello.ttf',
          bold: 'fontello.ttf',
          italics: 'fontello.ttf',
          bolditalics: 'fontello.ttf'
      }
  }
  

• add a style for icons: icon: { font: 'Fontello' }

• make a text paragraph: { text: '', style: 'icon' }, //icon wifi

• as the text you copy from the fontello-codes.css from the comments (not the escaped value)

If you need an icon within text, you need to nest text objects:

    text: [
        { text: '', style: 'icon' }, //icon gift
        " my present"
    ]

this puts out: “[gift icon] my present”
