tl.|¢tn>ªÏû•"q‚º†k‹ë²¶zño‰jÇ5»

i read file following command:

var input, file, fr;  input = document.getelementbyid('fileinput');  file = input.files[0];  fr = new filereader();  fr.onload = receivedbinary;  fr.readasbinarystring(file);       function receivedbinary() {     showresult(fr, "binary"); }  function showresult(fr, label) {     var result;     result = fr.result;     alert(result);      }

but it's happening problem. when see file content has been read, characters not loaded. following file after read:

tl.|¢tn>ªÏû"qºk벶zñojÇ5»

for example, realize symbol "•", between characters û , " not read.
