title: Ignoring spaces in length validation for JSON Schema
body: <p>Say you have this simple schema</p>
  
  <pre><code>{
    "type": "string",
    "minLength": 2,
  }
  </code></pre>
  
  <p>The value <code>"ab"</code> would be valid, but the value <code>"a "</code> or <code>"  "</code> would also be valid. Is there a way to ignore spaces when validating the length, so only <code>"ab"</code> is valid in this example?</p>
