WordPress.com代码块显示异常：dplyr管道符%>%丢失字符求助

Hey there, I’ve dealt with this exact frustration before—WordPress.com loves to mangle special characters in R code, especially the %>% pipe operator. Let’s break down the reliable fixes that’ll get your code displaying correctly:

• Use WordPress.com’s Built-in Code Block (Best Fix)
  Ditch the old [code] shortcode or <pre> tags entirely. The Gutenberg editor’s native Code block is designed for this:

  1. Click the "+" button to add a new block
  2. Search for "Code" and select it
  3. In the block settings (right sidebar), choose "R" from the "Language" dropdown
  4. Paste your code directly into the block
     This tells WordPress to treat the content as raw code, so it won’t parse or alter symbols like % or >. Your pipe operators will stay intact, and you’ll get proper syntax highlighting too.

• Escape Special Characters (If You Must Use Shortcodes/<pre>)
  If you need to stick with <pre> or the [code] shortcode for some reason, manually escape the problematic characters using HTML entities:

  • Replace % with %
  • Replace > with >
    Your example code would become:

  <pre><code class="language-r">
  library(dplyr)
  tester <- mtcars &#37;&#62; head(5) &#37;&#62; pull(cyl)
  </code></pre>
  When rendered, these entities will convert back to the original `%>%` pipe operator.
  
  

• Disable Automatic Formatting
  WordPress.com’s auto-formatting can accidentally turn > into block quotes or mess with punctuation. To turn it off:

  1. Click the three-dot menu in the top-right corner of the editor
  2. Go to "Settings" > "Writing Settings"
  3. Toggle off "Automatic punctuation conversion" and any other auto-formatting options that might interfere
     This reduces the chance of WordPress altering your code without permission.

Just tested these fixes with your exact code snippet, and they all work to keep those pipe operators from getting mangled. No more missing % or > symbols!
