Unicode to non-Unicode conversion—export

Here is the Java code for converting a Unicode-encoded text stream into Shi-JIS encod-

ing. Notice that this function does not return any information to the calling statement—it

merely reads in a text stream and outputs to another text stream.

File o = new File("output.sjs");

FileOutputStream tmpout = new FileOutputStream(o);

BufferedWriter out = new BufferedWriter(new OutputStreamWriter(tmpout,"Shift_JIS"));

Aer the BueredWriter object out is established, Unicode data that is subsequently out-

put is automatically converted to Shi-JIS encoding.

out.println("\u6CB3\u8C5A");

out.close();

e two Unicode characters 63 () and 85 () that are fed to the println()

method become Shi-JIS <89 > and <93 8> in the output le called output.sjs. Creat-

ing a UTF-8–encoded output le is accomplished in the same way, but the UTF-8 charset

designator should be used instead of Shi_JIS.

It is also possible to output directly in Unicode, demonstrated as follows:

PrintWriter out = new PrintWriter (

new BufferedWriter (

new OutputStreamWriter (

new FileOutputStream("output.ucs"), "UTF-16BE"

)

)

);

We can then output the same Unicode characters, without any code conversion applied,

as follows:

out.println("\u6CB3\u8C5A");

out.close();

is time, the output is exactly 63 () and 85 ().
