How to save Chinese Characters to file with java?

Question

I use the following code to save Chinese characters into a .txt file, but when I opened it with Wordpad, I couldn\'t read it.

StringBuffer Shanghai_StrBuf =

Here's one way among many. Basically, we're just specifying that the conversion be done to UTF-8 before outputting bytes to the FileOutputStream:

String FileName = "output.txt";

StringBuffer Shanghai_StrBuf=new StringBuffer("\u4E0A\u6D77");
boolean Append=true;

Writer writer = new OutputStreamWriter(new FileOutputStream(FileName,Append), "UTF-8");
writer.write(Shanghai_StrBuf.toString(), 0, Shanghai_StrBuf.length());
writer.close();

I manually verified this against the images at http://www.fileformat.info/info/unicode/char/ . In the future, please follow Java coding standards, including lower-case variable names. It improves readability.
