Published: Oct 19, 2026 | Updated: Oct 19, 2026 | About (Japanese)

Key points
  • Check the detected encoding
  • Change the reading manually
  • Convert once it looks right

Convert Text Encoding guesses the encoding from the start of the file and its byte patterns.

Steps

  1. Choose the file and read the "Detected:" line
  2. If it is garbled, pick another "Current encoding"
  3. When the preview looks right, convert
Short files are easy to misjudge. Check the preview and choose manually if needed.
