sql server - Java Resultset Not Showing Unicode (Chinese) Characters, But Showing as Question Marks -

-

i have following issue. java resultset not showing unicode (chinese) characters, showing other characters. sure characters stored/showing in microsoft sql server (as nvarchar).

so seems retrieving issue. here code:

protected string getstringvaluenonulls(resultset rs, string colname) {

        string ret = rs.getstring(colname);          ret = new string(ret.getbytes(), "utf8");          system.out.println(ret);

... output print statement:

so (so in db)

??? (张先生 in db)

??????9999 ( 建国门外大街9999 in db)

?? (北京 in db)

100010 (100010 in db)

it showing english/ascii characters not chinese characters. noticed number of chinese characters equal question marks replaces with.

i have tried before plain getstring(), , doing getbytes() conversion both producing same results.

is missing, or maybe issue driver? please help.

----------------i added connection, didn't help:

class.forname("com.microsoft.sqlserver.jdbc.sqlserverdriver");

string connectionurl = "jdbc:sqlserver://127.0.0.1:1433;database=mydb;user=myuser;password=mypass;useun‌​icode=true;characterencoding=utf-8";

connection con = drivermanager.getconnection(connectionurl);

still getting same questions marks chinese characters.

regards.

ok, figured solution. problem java & utf8 encoding not being able print & write.

(not driver issue) first must use print stream if outputting (file or console): //console

` string ret = rs.getstring(colname);

        printstream out = new printstream(system.out, false, "utf8");  //this key          out.println(ret); `

//file

private static void writeutf8tofile(file file, boolean append, string data) throws ioexception { boolean skipbom = append && file.isfile() && (file.length() > 0); closer res = new closer(); try { outputstream out = res.using(new fileoutputstream(file, append)); writer writer = res.using(new outputstreamwriter(out, charset .forname("utf-8"))); if (!skipbom) { writer.write('\ufeff'); } writer.write(data); } { res.close(); } }
