Common Mistakes to Avoid

⚠️

Case not preserved

Solution: Replacing "a" with "e" may not handle "A" → "E". Check case-preservation options.

⚠️

Character mapping mismatch

Solution: If Find has 5 chars and Replace has 3, behavior varies by tool. Match lengths or check docs.

⚠️

Special characters in replacement

Solution: Regex special chars like . or * may need escaping. Check if tool uses regex.
