one more update: if i add the following two lines to my _vimrc, then
the ucs-2le text file works:
set fileencodings+=ucs-2le
set encoding=utf-8
note that both need to be set before i edit the file. once i load the
file, setting them no longer helps.

Of course:
- Vim needs to be able to represent Unicode codepoints in memory (":set
encoding=utf-8"). This must be done before any attempt to read the file.
- Vim needs to know how to detect the encoding. This can be done in several
ways:
* if 'fileencodings' *begins* with "ucs-bom", any Unicode encoding with BOM
will be recognised.
* if you use ":e ++enc=ucs-2be filename", the file will be interpreted
according to big-endian UCS-2
* if 'fileencodings' contains "ucs-2le", and anything preceding it checks
"invalid" for that file, then the file will be read as little-endian UCS-2 if
it contains no invalid bytes for that encoding.
Of course, if you change 'fileencodings' after the file has been read, it is
too late.
You also need to set a font containing the glyphs for whatever codepoints
you'll want to see. This is not a trivial problem in multilingual file: e.g.,
I know no fixed-width font having both Chinese and Arabic glyphs. Setting the
font is done in gvim by means of the 'guifont' option; console Vim uses
whatever font is set by the hardware text console or by the software terminal
emulator.
See:
:help 'encoding'
:help 'fileencodings'
:help ++opt
:help mbyte.txt
:help 'guifont'
