=== spell checker ===
  :setlocal spell spelllang=en_us

Put map commands in your .vimrc file to associate function keys with turning on and off the spell checking:
  map <F10> <Esc>:setlocal spell spelllang=en_us<CR>
  map <F11> <Esc>:setlocal nospell<CR>

=== windows encoding ===
<file>
Your file is in little-endian UTF-16. With 'encoding' set to UTF-8, load
it using

:e ++enc=utf-16le filename

If the first two bytes in the file are 0xFF 0xFE (the UTF-16le encoding
marker, also known as the BOM for "byte order mark"), then the encoding can
be recognised automatically if your 'fileencodings' start with ucs-bom
(i.e., with ":set fencs^=ucs-bom"). -- Normally, if your 'encoding' is set
to UTF-8, 'fileencodings' should be set to something like
"ucs-bom,utf-8,default" (for Vim 7) or "ucs-bom,utf-8,latin1" (for Vim6,
replace "latin1" by the 8-bit encoding you use most often).

See
:help ++opt
:help mbyte-encoding
:help encoding-values
:help 'fileencodings'
/"ucs-bom"
:help 'bomb'
especially the last paragraph
:help :set^=

===== Convert Windows UTF-16 files to UTF-8 =====
Log files come from Windows in UTF-16.  vim can handle it with the above.  cat can display it fine, but less and vim prefer UTF-8.
  iconv -f UTF-16 -t UTF-8 drwtsn32.log |less
