Need to save as UCS-2 LE BOM ini file

Hi,

I built an unique HTML page (I integrated FileSaver.js content at the HTML page end) to easy edit language.ini file of Jingle Palette ( https://github.com/nagyrobi/Jingle_Palette/blob/master/language.ini ).
But when I use the FileSaver functions, the file is saved as UTF-8 (can see it with Notepad++).
The Jingle Palette softare does'nt not recognize special characters.
If I look the original language.ini file, with Notepad++, I can see the encdogind is UCS-2 LE BOM .

The code I use in the function to create the downloadable file :
```
var blob = new Blob([contenu_ini], {type: "text/plain;charset=UTF-8"});
saveAs(blob, "language.ini");
```

Tried to change charset for
```
var blob = new Blob([contenu_ini], {type: "text/plain;charset=UCS-2"});
saveAs(blob, "language.ini");
```
or
```
var blob = new Blob([contenu_ini], {type: "text/plain;charset=ISO-10646-UCS-2"});
saveAs(blob, "language.ini");
```

The output file still in UTF-8 .

Can you help me please ?
Thanks :)
