How can I create a cp932 encoded text file on Ubuntu?

gedit, "Save as" has an option to save it with a different encoding.

After that it should accept Japanese chars.

as seen here:

~/Desktop$ file test.txt
test.txt: DBase 3 data file with memo(s)

Command line

• convert a file to cp933:

  recode cp932 {filename}
  

  or

  iconv -f utf8 -t cp932 {filename} > {newfilename}
  

  You probably need to install recode with sudo apt-get install recode If you do

   touch {filename}
   recode cp932 {filename}
  

  you create an empty file and should be able to add cp932 chars to the file.

• If you use vim place the following in your /etc/vim/vimrc or ~/.vimrc file:

  set encoding=cp932
  set fileencoding=cp932
  

  and the system will save the with cp932.
