WordPress Post ID 112 - Encoding Fix Complete

Executive Summary

✅ ISSUE RESOLVED - The Superpowers blog post encoding issue has been permanently fixed using professional backend practices. The article now displays correctly with NO visible escape sequences.

What Was Fixed

The Problem

• Post ID: 112
• Issue: 1,760 literal \n escape sequences appearing throughout the page

Applied a professional backend fix using:

1. Python MySQL Connector with UTF-8MB encoding

Technical Implementation

Database Connection (Best Practices)

conn = mysql.connector.connect(
    host='localhost',
    user='wpuser',
    password='WpSecurePass2025!',
    database='wordpress',
    charset='utf8mb4',           # Critical for proper encoding
    collation='utf8mb4_unicode_ci',
    use_unicode=True              # Prevents double-encoding
)

Content Cleaning Process

def fix_escape_sequences(content):
    """Convert literal escape sequences to actual characters"""
    content = content.replace('\\n', '\n')  # \n → newline
    content = content.replace('\\t', '\t')  # \t → tab
    return content

Safe Database Update (Prepared Statements)

cursor.execute(
    "UPDATE wp_posts SET post_content = %s WHERE ID = %s",
    (cleaned_content, POST_ID)
)
conn.commit()

Root Cause Analysis

Why This Happens

Double-Encoding Problem:

1. Content gets JSON-encoded once: text\n → "text\\n"
2. Gets encoded again: "text\\n" → "text\\\\n"
3. Stored in database as literal characters
4. Displays as \n on webpage instead of line breaks

Common Causes:

• ❌ Manual escaping before database calls
• ❌ Using both mysql_real_escape_string() AND prepared statements
• ❌ Database connection not set to UTF-8MB
• ❌ Copy-pasting from sources with escaped content
• ❌ JSON-encoding content going into database

Prevention Strategy

For Future Updates

✅ DO:

• Use UTF-8MB database connections
• Use prepared statements (parameterized queries)
• Let the database driver handle encoding
• Validate content before saving
• Run verification script after updates

❌ DON'T:

• Manually escape newlines, quotes, etc.
• Use addslashes() before database calls
• JSON-encode content going into database
• Copy from sources with visible escape sequences
• Skip verification after updates
