write text file mix between arabic and english

Question

i'm trying to write in text file sentences that contains Arabic and English but the problem that both languages have direction RTL and LTR so the output text file don't save the order of the words and some words come before each other that is wrong, the problem fixed when i change the text direction from the notepad or any text editor, is there any way to fix this using java?

Answer 1

As I explained in my comment on your previous question, Unicode text files store the characters in logical order. There is a documented algorithm for how to handle bidirectional text, and control characters you can insert into the text stream to give hints to the renderer about, for example, where to attach punctuation when you have an Arabic quotation in the middle of an English sentence.

But ultimately the choice of the top-level "predominant" direction of the text as a whole is a matter for the component that is displaying the text rather than something that the text itself can control - the renderer has to decide whether it's dealing with a mostly-English paragraph containing some bits of Arabic or vice-versa.

For example, suppose I have a file containing the following logical sequence of characters (in line with the conventions in the bidi algorithm spec I use lowercase for left-to-right characters such as English and UPPERCASE for right-to-left characters such as Arabic):

abc def GHI! JKL mno? PQR

A viewer configured to treat the text as predominantly LTR would render this as

abc def LKJ !IHG mno? RQP

whereas a viewer configured to treat it as predominantly RTL would render exactly the same text as

                                      RQP ?mno LKJ !IHG abc def

(in the absence of control characters to the contrary the punctuation that lies at the boundary between a LTR and RTL segment will attach to the one that matches the overall paragraph direction)

i think you can just set the charset to UTF-8 and youll get the order of the words right. take a look at this

Writer out = new BufferedWriter(new OutputStreamWriter(new FileOutputStream("Output.txt"), "UTF-8"));
try {
        out.write("1.");
        out.write("English ");
        out.write("2.");
        out.write("عربي ");
        out.write("3.");
        out.write("Hey ");
        out.write("4.");
        out.write("السلام ");
    } finally {
        out.close();
    }

File f = new File("Output.txt");
Scanner fileprint = new Scanner(f);

while(fileprint.hasNext()){
    System.out.println(fileprint.next());
}
