title: How to use Maybe version of v8::String::NewFromUtf8?
body: <p>I'm trying to build a native node module against Node 12 and am getting errors such as:</p>
  
  <pre><code>warning: ‘static v8::Local&lt;v8::String&gt; v8::String::NewFromUtf8(v8::Isolate*, const char*, v8::String::NewStringType, int)’ is deprecated: Use maybe version [-Wdeprecated-declarations]
  </code></pre>
  
  <p>On code such as:</p>
  
  <pre><code>v8::String::NewFromUtf8(v8::Isolate::GetCurrent(), "some string")
  </code></pre>
  
  <p>I understand the error, but based on the v8::String docs, I can't figure out how to specify the Maybe version... The prototypes look the same. How can I use the Maybe version of this function?</p>
