Quick summary

The "copy post" or "duplicate post" functionality may incorrectly strip the \ character from post content.

This affected character is U+005C Reverse Solidus character or "backslash."

Steps to reproduce

1. Create a post with content like this:

   <!-- wp:code -->
   <pre class="wp-block-code"><code>\t is a tab</code></pre>
   <!-- /wp:code -->

   That is a Code block with the text \t is a tab.

2. Save the post.

3. From the post edit view, click "Duplicate" on the post.

4. A post is created where the text is now t is a tab:

   <!-- wp:code -->
   <pre class="wp-block-code"><code>t is a tab</code></pre>
   <!-- /wp:code -->

 <!-- wp:code -->
-<pre class="wp-block-code"><code>\t is a tab</code></pre>
+<pre class="wp-block-code"><code>t is a tab</code></pre>
 <!-- /wp:code -->

This seems to happen regularly with the \ character:

• \t -> t
• \n -> n
• \f -> f
• \\ -> \
• \9 -> 9
• \ -> (space)
