title: How to write to file text containing a double-quote without new line
body: <p>I need to write the following string without new line to the new file:</p>
  
  <blockquote>
  <pre><code>R"(
  </code></pre>
  </blockquote>
  
  <p>I have tried:</p>
  
  <pre><code>echo|set /p = R"( &gt; ..\web\index.min.html
  echo|set /p = R^"( &gt; ..\web\index.min.html
  echo|set /p = R\"( &gt; ..\web\index.min.html
  </code></pre>
  
  <p>With no result.</p>
  
  <p>But if I write:</p>
  
  <pre><code>echo|set /p = R""( &gt; ..\web\index.min.html
  </code></pre>
  
  <p>I get:</p>
  
  <blockquote>
  <pre><code>R""(
  </code></pre>
  </blockquote>
  
  <p>Two double-quotes instead of one.
  How can I solve my problem?</p>
