Use the following rules and guidelines when you configure encodings:
To increase performance, set the working encoding to be the same encoding as the output document.
Set the input encoding to the same encoding as the input document.
Set the output encoding to the same encoding as the output document.
For languages that have multiple-byte characters, set the working encoding to UTF-8. For the input and output encoding, you can use a Unicode encoding such as UTF-8 or a double-byte code page such as Big5 or Shift_JIS.
