  ```
2. Use "Save Output As" to export the output as an HTML file.
3. Open the exported HTML file.

OBSERVED RESULT
The exported line ends with an extra character, and additional null charact=
ers
are present between CJK characters in the HTML file.

The line should end with no extra characters, and the file should not conta=
in
null characters.
