JavaScript - Generating .SRT file

Question

I made a script to edit my subtitles in my browser. not in text editors etc.. so i did everything and i am at the final stage of it, when i click the button 'save' to download my edited version, My browser automatically downloads the SRT file as expected, But however the subtitle is shown as 'Little Square Boxes' instead of the arabic text i wrote and edited..

What i see on VLC Video Player:

What i have in my SRT File:

1
00:00:05,796 --> 00:00:06,888 
چیرۆكم پێ بڵێ

2
00:00:07,048 --> 00:00:08,265 
چیرۆكم پێ بڵێ

3
00:00:08,424 --> 00:00:09,846 
چیرۆكم پێ بڵێ

Code used to generate edited version of subtitle:

    // Function to download data to a file
function download(data, filename, type) {
    var file = new Blob([data], {type: type});
    if (window.navigator.msSaveOrOpenBlob) // IE10+
        window.navigator.msSaveOrOpenBlob(file, filename);
    else { // Others
        var a = document.createElement("a"),
                url = URL.createObjectURL(file);
        a.href = url;
        a.download = filename;
        document.body.appendChild(a);
        a.click();
        setTimeout(function() {
            document.body.removeChild(a);
            window.URL.revokeObjectURL(url);  
        }, 0); 
    }
}

And then:

download(all_str,"anyth.srt","text/html")

The string all_stris my new edited version of the subtitles.. all separated by new lines, just like the text editor version

The subtitle works with english and other languages except arabic

Things i have done to fix this:

• Changed text/html to text/plain and text/plain utf-8 and text/plain charset=utf-8 but didn't work
• Changed VLC Player's Encoding type from Universal to utf8 but didn't work

I think this has to do something with the encoding type, something i missed or don't know? please fill me in

Answer 1

You're doing everything right, However most of our current operating systems run on Windows-1256.. I have tested your code with this unicode, it works with Arabic and Persian:

Just change:

text/plain;charset=windows-1256
