java - Cannot write chinese characters to a filename -

public static void main(string[] args) throws ioexception {     scanner in = new scanner(system.in);     string filename = in.nextline();      writer out = new bufferedwriter(new outputstreamwriter(             new fileoutputstream("c:/temp/"+filename+".txt"), "utf-8"));//ex thrown     out.close(); } 

i'm trying create writer can handle chinese characters file name. can create file called 你好.txt example.

however filenotfoundexception above code, works fine english characters not chinese characters.

i followed answers here: how write utf-8 file java? produce above code doesn't work.

anyone know how can accomplish this?

stack trace:

using nio:

path path = paths.get("c:/temp/"+filename+".txt");//throws ex charset charset = charset.forname("utf-8"); path file = files.createfile(path); bufferedwriter  bufferedwriter = files.newbufferedwriter(file, charset); bufferedwriter.close();

i have found out problem related character encoding of eclipse console , not related java.

i have used same code , used run configuration differently shown below,

now after running program got following output in console,

exception in thread "main" java.io.filenotfoundexception: c:\temp\??.txt (the filename, directory name, or volume label syntax incorrect)     @ java.io.fileoutputstream.open(native method)     @ java.io.fileoutputstream.<init>(fileoutputstream.java:206)     @ java.io.fileoutputstream.<init>(fileoutputstream.java:95)     @ test.main(test.java:21) 

conclusion : here iso-8859-1 encoding in run configuration scanner not able read character console because console has different character encoding , have ?? filename.

please change character encoding console, firmly believe using ide. may have changed or console inherited character encoding not suppose encode characters.
