How to Convert a File to UTF-8

Encoding non-English messages in UTF-8 ensures proper rendering across various platforms.

Unicode Transformation Format 8 (UTF-8) is an encoding scheme that allows applications to properly display complex characters such as Japanese kanji or currency symbols. Many people use UTF-8 encoding to send and receive non-English email messages. Because of its flexibility, many developers prefer to use UTF-8 to create cross-platform applications and design commercial websites. If you wish to convert files to UTF-8, use Notepad or any plain text editor that supports Unicode. You may also use Windows PowerShell to rewrite files using UTF-8 encoding.

2. Open the "File" menu and choose "Save As."

3. Enter your preferred file name. Click the drop-down menu beside "Encoding" and then choose "UTF-8." Click the "Save" button.

Converting Any File to UTF-8 Using Windows PowerShell
