I’ve only answered your questions these days.
Change the code if the code is out of order:

"Default encoding {{{)
 if has('vim_starting')
 if &encoding !  =?  'utf-8'
 let &termencoding = &encoding
 endif
 set encoding=utf-8
 set fileencoding=utf-8
 set fileencodings=ucs-bom,utf-8,default,cp936
 endif
 " }}} end
