My data adapter is .NET implementation. Here is code to update to LS client:
Dictionary<string, byte[]> data = new Dictionary<string, byte[]>();
data.Add("fieldname1", new byte[] { 65, 66, 67 });
_listener.Update("item1", data, false);
As you mentioned in your docs here http://www.lightstreamer.com/docs/cl....html#getValue, this function returns a String.

How do I properly convert from String to byte[] in my Javascript code?

Should I use String.getBytes("ISO-8859-1")? Is it platform-independent?

Thanks in advance,
