Saving a file in a with a file name containing Japanese Characters

Question

Hi,
I hope some genius out there comes up with the solution to this problem
Here it is :
I am trying to save some files using a java program from the command console , and the file name contains japanese characters. The file names are available to me as string values from an InputStream. When I try to write to a File Object containing the japanese characters , I get something like ?????.txt . I found out that I am able to save the files using the unicode value of the java characters.
So I realize that the trick is to convert the streaming japanese characters , character by character into their respective unicode value and then Create A File Object with that name. The problem is -> I cant find any standard method to convert these characters into their unicode values. Does anyone have a better solution ? Remember , its not writing japanese characters to a file , but creating a file with japanese characters in the file name !!!!
Regards

Answer 1

retrive a byte array out of the input Stream and store the values in String using the condtructor
String(byte [] bytes, String enc)
where encoding would be Shift_Jis for japanese I guess.
Now to understand this concept basically all the Strings are unicode however when you are passing a byte array String has no means to know what is the encoding of the byte array, which is being used to instantiate the String value so if no encoding is specified it takes the System value which is mostly iso-8859-1. This leads to displaying ?
However in case you know the encoding of the array specifying that in the constructor would be a real help.
