title: Regexp replacement character
body: <p>I created a CSV file in Go and I have to add quotation marks(&quot;) in every column, I added these but this time, <strong>CSV programming adds extra(double) quotation marks in <em>comment</em> column</strong> (if there is the comma(,) in column)</p>
  <p>My CSV</p>
  <pre><code>comment_ID&quot;,&quot;post_ID&quot;,&quot;product_SKU&quot;,&quot;comment_author&quot;,&quot;author_mail&quot;,&quot;author_location&quot;,&quot;date&quot;,&quot;comment&quot;
  &quot;100&quot;,&quot;60574&quot;,&quot;VID17&quot;,&quot;Jordi&quot;,&quot;&quot;,&quot;&quot;,&quot;2021-06-02 16:20:30&quot;,&quot;&quot;My son likes this video, good job&quot;&quot;
  &quot;101&quot;,&quot;60574&quot;,&quot;VID18&quot;,&quot;Scarlett,&quot;&quot;,&quot;&quot;,&quot;2020-12-29 23:06:32&quot;,&quot;&quot;I don't like this video, it may be better&quot;&quot;

  <p>I need CSV like this (there is not double quotation in comment columns&quot;</p>
  <pre><code>comment_ID&quot;,&quot;post_ID&quot;,&quot;product_SKU&quot;,&quot;comment_author&quot;,&quot;author_mail&quot;,&quot;author_location&quot;,&quot;date&quot;,&quot;comment&quot;
  &quot;100&quot;,&quot;60574&quot;,&quot;VID17&quot;,&quot;Jordi&quot;,&quot;&quot;,&quot;&quot;,&quot;2021-06-02 16:20:30&quot;,&quot;My son likes this video, good job&quot;
  &quot;101&quot;,&quot;60574&quot;,&quot;VID18&quot;,&quot;Scarlett,&quot;&quot;,&quot;&quot;,&quot;2020-12-29 23:06:32&quot;,&quot;I don't like this video, it may be better&quot;
  </code></pre>
  <p>My Golang Code</p>
  <pre><code>RegContent := regexp.MustCompile(`&quot;,&quot;&quot;[A-Za-z0-9]`)
  newRegexp := RegContent.ReplaceAllString(CSV_Contents, `&quot;,&quot;`)
  fmt.Println(&quot;PLAY: &quot;, newRegexp)
  err = ioutil.WriteFile(path, []byte(newRegexp), 0)
  if err != nil {
      fmt.Println(&quot;error: &quot;, err)
  }
  </code></pre>
  <p>Output</p>
  <pre><code>&quot;son likes this video, good job&quot; //(Missing My)
  &quot;don't like this video, it may be better&quot; //(Missing I)
  </code></pre>
