When Unicode characters are received, the message being passed is null

[pradsin]

I noticed that it Unicode characters are passed the event raised by sipml passed empty message. Though the websocket frame shows the exact message.

Here are test strigs

"!"#$%&'()*+,-./0123456789:;<=>?@ABCDEFGHIJKLMNOPQRSTUVWXYZ[]^`abcdefghijklmnopqrstuvwxyz{|}~"cª«¬-r_°±²3'µ·,1º»¼½¿AAAAÄÅÆÇEÉEEIIIIDÑOOOOÖxOUUUÜY_ßàáâaäåæçèéêëìíîïdñòóôoö÷oùúûüy"
