title: Is there any way to render custom symbols with gdx-freetype?
body: <p>I want to draw symbols u2680-u2685, but when one of the fields gets a string with one of that symbols, it renders everything, except this symbol.</p>
  
  <p>I know one solution to this problem <code>FreeTypeFontParameter</code> has field <code>characters</code>. And every symbol from this string will be rendered properly.
  But in this case, I need to put ALL Latin symbols and all other symbols in this string one at a time. This is not cool.</p>
  
  <p>Anyone know the better solution to this problem? Maybe without <code>characters</code>, or with auto putting range of symbols to this string. </p>
