you have to Encode your outPut/input Straem with proper Charset

byte input/outputSteam[] = myString.getBytes("ISO-XXXX-X"); 
String myEncodedString = new String(input/outputSteam, "ISO-XXXX-X");

//NOTE X == equals Numbers represents chinese Charset from Native OS


First of all, you would have to be able to generate Unicode and not ASCII code.
A *.csv file is a TEXT file, which uses ASCII code.
You cannot use Unicode in a text file and use a regular text editor to view.
You would need a special text editor that can handle Unicode.
(One may exists, but I've never heard of one.)
MAYBE MS Excel can import a *.csv file and convert the Unicode,
but you would have to try this.


@hfx642 I see that you are from native ACSII languages, Native OS and especially Win doesn't care about that and pretty ignore file saves in Unicode/UTF8/UTF16 in case that Native OS is Localized (but this file is backward compactible with any of programing language, but not readable in MsOffice ...),

(for for readable document in MsOffice) I must remove (convert) all non-ACSII chars to ACSII, or Encode (File, Stream, whatever user services from/to Native OS) with cp1250/ISO 8859-2, then is for Win OS pretty readable, but not with backwards compactible for PL without encode back to Unicode/UTF16 (majorities of todays PL is based on Unicode/UTF8/UTF16)
