ANSI<>UNICODE and reverse

[Paolo Baruffa]

Hi all!
I need to perform ANSI/UNICODE commands in my GVIM.
I read many docs on the web about and I did set these:

"------------------------------------------
" .vimrc includes
"----------------------
:set ffs=dos,unix,mac " autosense Dos,Unix,Mac
:set fileencodings=ucs-bom,utf-8,latin1 " autosense coding
" (no fileencoding is set in .vimrc)

"------------------------------------------
" my menu includes
"----------------------

:set fileencoding=latin1<CR><Esc>:set ff=dos<CR>:w!<CR> " ANSI Dos
:set fileencoding=utf-8<CR>:w!<CR><Esc> " UNICODE

"-------------------------------------------

but they don't work correctly (I check the files with an
other editor)...

1) I open an ANSI file with GVim, I ask ":set fileencoding"
and the file appears as "utf-8"

2) conversion between ANSI <> UNICODE and then reverse likes
right ("converted" in bottom status line), but refreshing
the file on the other editor I see the same coding...

Does anybody can help, pls?

What's the value for the option "encoding" ?

if the "encoding" is set to utf-8 when you don't set "fenc" , the file 

will open with the same encoding as what you set to enc , which should 

become 'utf8'

 

2) conversion between ANSI <> UNICODE and then reverse likes
right ("converted" in bottom status line), but refreshing
the file on the other editor I see the same coding...

What do you mean for the "The same coding "?

The coding is always ANSI or UNICODE?

And before this , there is something should be mentioned.

UTF-8 is a variable-length character encoding for UNICODE , and 

if you original file is ansi encoding ,  when it is convert to utf8 ( without BOM),

the file should be same ( seems like no convert ). Because utf8 uses the single

octet encoding only for the 128 US-ASCII characters  which is the same as

when it is encoding with ansi.
