Hi Christian,

Thanks for your effort on this issue.

We have a novnc server running and access the console of vms on other
servers via the novnc server.

I also added a method in novnc to send a string via keyevent. The code
looks like

+        sendString : function(str) {
+            if (this._rfb_state !== "normal" || this._view_only) { return 
false; }
+            Util.Info("Sending: "+str);
+            var arr = [];
+            for (var i = 0; i < str.length; i++ ) {
+                var char = str.substring(i, i + 1);
+                var code = char.charCodeAt(0);
+                if (shifted[char]) RFB.messages.keyEvent(this._sock, 
XK_Shift_L, 1); // Shift
+                RFB.messages.keyEvent(this._sock, code, 1); // (key)
+                RFB.messages.keyEvent(this._sock, code, 0); // (key)
+                if (shifted[char]) RFB.messages.keyEvent(this._sock, 
XK_Shift_L, 0); // Shift
+            }
+
+            this._sock.flush();
+        },
+

In my testing, only 8 chars can be accepted via novnc even the string is much 
longer.
As described in [1], the patch fixes the issue. I verified it is working.
