title: How do I bind Character to a TextField?
body: <p>I've found an example of how to bind Integer to a TextField:</p>
  
  <pre><code>Binder&lt;Person&gt; b = new Binder&lt;&gt;();
  b.forField(ageField)
      .withNullRepresentation("")
      .withConverter(new StringToIntegerConverter("Must be valid integer !"))
      .withValidator(integer -&gt; integer &gt; 0, "Age must be positive")
      .bind(p -&gt; p.getAge(), (p, i) -&gt; p.setAge(i));
  </code></pre>
  
  <p>The problem is - there is no StringToCharacterConverter and if have an error if I bind fields as is. The error is:</p>
  
  <pre><code>Property type 'java.lang.Character' doesn't match the field type 'java.lang.String'. Binding should be configured manually using converter.
  </code></pre>
