> One symbol in national language expanded to 4 bytes when UCS2 character encoding used.
> So, size of 256 bytes for receiving buffer {{buf}} in function {{do_monitor_phone}} is not enough for incoming UCS2 encoded SMS, when last is longer than 50 national symbols. I suggest to set size of this buffer to 350 bytes, instead of current 256 bytes.
> Such modification will make incoming SMS in UCS2 encoding not to be truncated. Provided patch reclaims truncation only for incoming SMS, and not affect outgoing SMS.
