Fix UTF-8 Encoding in Notepad++
Understand UTF-8, BOM and how to avoid corrupted text.
Quick answer
Check the Encoding menu, determine the file's actual encoding, and convert a copy only after verifying the characters display correctly.
When to use this feature
Changing how bytes are interpreted is different from converting the file to a new encoding.
Step-by-step instructions for Windows users
- Open Notepad++ on Windows 10 or Windows 11 and save a backup of the file you plan to edit.
- Check the Encoding menu, determine the file's actual encoding, and convert a copy only after verifying the characters display correctly.
- A UTF-8 BOM may matter to certain scripts and legacy applications; choose based on the receiving system.
- Review the result and save a separate copy before replacing the original file.
Important details and compatibility
A UTF-8 BOM may matter to certain scripts and legacy applications; choose based on the receiving system.
Menu labels can differ between versions, and plugins may require a compatible build. Check the application settings on your own PC rather than assuming all installations have the same options.
Common mistakes and safety
Repeated conversions of already corrupted text can make recovery harder; retain the original bytes.
If the result differs from what you expected, undo the change, reopen the original copy, and repeat the steps with a smaller sample.
