Patch from upstream

Starting from version 2.2 tmux uses system functions to work with Unicode. On
FreeBSD, wcwidth() returns -1 on some characters(like ''), so tmux cannot
correctly draw this. Step to reproduce - type "echo '\U+E0A1'", you must see
'' symbol but in tmux echoed empty line on 11-STABLE. This is a problem with
FreeBSD system locale implementation, but upstream have workaround. Patch from
upstream attached.
