Answer 1

To export CSV containing multibyte characters and make it readable on text editor and Excel in multiple OS platforms (Windows, Linux, MacOS), the following rules should be applied:

1. Separate the field with tab instead of comma (so that Excel on MacOS can properly display the generated CSV file)
2. Encode the string / content with UTF-16 little endian (UTF16-LE) instead of UTF-8
3. Add byte order mark (BOM) 0xFEFF as specified in RFC2781 section 3.2 at the beginning of the serialized stream to explicitly provide "signature" of content encoded with UTF16-LE

Further elaboration, use cases and sample code with NodeJS can be seen in this article.
