Create a file with "Japanese(Shift-JIS)" encoding
vt
I need to create a file with "Japanese(Shift-JIS)" in .NET. By default, i
am getting a UTF-8 encoding.
How do i do that? Unfortunately, help is not clear.
Regards

// you can use

// to get a an encoder for your codepage

StreamWriter writer = new StreamWriter(path,false,enc);
That should be it

Well, it is clear, but you're just not looking in the right places :)
.NET only supports the following file encodings:
ASCII
UTF-7
UTF-8
Unicode
Big Endian Unicode
I don't know what Japanese (Shift-JIS) is, but if it doesn't
fall into one of those, then you'll have to write your own
encoder/decoder by overriding:
System.Text.Encoding
-c
Don Dumitru
I don't think that's entirely accurate. You should be able to get an
encoder for an arbitrary codepage (assuming that the codepage is installed
on the system) by calling System.Text.Encoding.GetEncoding(number); where
number is the number of the codepage you want.
Shift-JIS appears to be codepage 932. Under just what conditions it
actually gets installed on any particular machines, I don't know. (I would
hazard a guess that it has to do with what version of Internet Explorer is
installed on the machine, since that's where most of the MLANG support seems
to get packaged.)

I thought it was a seperate encoding altogether.
Codepages are for Unicode, so he'd be using the Unicode encoding
with a specific code page for translation.

AFAIK the name is "iso-2022-jp".

The documentation even uses Japanese Shift-JIS as an example.
From the documentation:
"A specific code page might not be supported by certain platforms. For
example, the Japanese shift-jis code page (code page 932) might not be
supported in the United States version of Windows 98. In that case, the
GetEncoding method throws NotSupportedException when the following C# code
is executed:
Encoding enc = Encoding.GetEncoding(932); "
Hopefully it will work on a Japanese OS.

kevin,
I am using vb.net and 'system.text' namespace.
Dim fl As File
I am using f1.createtext to create a file. It creates in UTF-8 format
I am trying to also use f1.create , but i am not sure how to set the file
encoding set to Shift_Jis
I have been trying for sometime but end doesn't seem to be near.

If that encoding isn't present on the system,
(Shift-JIS isn't present on US systems by default),
you'll get a NotSupportedException from your call
to Encoding.GetEncoding().
You may or may not want to trap that specifically
and handle it appropriately.

yes, I used Encoding enc = Encoding.GetEncoding(932) to get the encoding,
but
how do i set that to a file? or a streamwriter ? There is an encoding
property there, but it is readonly.

There are several constructors for StreamWriter and 2 or 3 of
them take the encoding.
For example:
StreamWriter(string path, bool append, Encoding encoding)

(sw).
I opened the streamwriter , as discussed below, but when i pass a string
(the string has some Katakana characters)
to sw.writeln(str) and close the stream writer, it doesn't still create a
file with JIS encoding.
I am sure about that because when i open the doc, it does'nt ask me about
encoding type.
Is sw.writeln doing something strange here?

with StreamReader (don't specify an encoding and it should
determine it automagically).
Then print out the Encoding property of the StreamReader
and see what it says. It should say something like 932 or
"Shift-JIS". If it says anything else, then something else
is wrong.
Let us know what it says.

It looks like the file i saved, is not saved as SHIFT-JIS or the katakana

Not sure where the issue is ..

When you open the StreamReader, use this constructor:
StreamReader(string filePath, Encoding encoding)
When you read it, specify the 932 encoding and see if you
get better results.

encoding, i get the Shift-JIS. The file is still messed up.
Here is where the issue lies i think ..
1. To save a japanese string in the database, we need to you unicode
(nvarchar, nchar).
2. When We retrieve the unicode string and insert it in a streamwriter with
Shift-JIS encoding, it may not work correctly.
I think we need to convert the unicode string into a Shift-Jis string and
then insert into the file ..
Not sure though .

views of Unicode, so it shouldn't matter one way or the
other.
My guess is that StreamReader/Writer is/are screwed up
somehow.

I wrote
string hiragana = "\u3041\u3042\u3043";
string katakana = "\u30a1\u30a2\u30a3";
to a file using Japanese(Shift-JIS) encoding and made a hex dumb
of the file.
The result was :
82 9F 82 A0 82 A1 0D 0A 83 40 83 41 83 42 0D 0A
And there were no problems reading the strings back from the file.
( If you use utf8 for encoding you get :
EF BB BF E3 81 81 E3 81 82 E3 81 83 0D 0A E3 82
A1 E3 82 A2 E3 82 A3 0D 0A
)
This is the code I used to write the strings in the file and read
them back :
Encoding encJ = Encoding.GetEncoding(932);
FileStream fs = new FileStream("japan.txt", FileMode.Create);
StreamWriter sw = new StreamWriter(fs, encJ);
sw.WriteLine(hiragana);
sw.WriteLine(katakana);
sw.Close();
fs.Close();
StringBuilder sb = new StringBuilder();
sb.AppendFormat("{0}\n{1}\n",hiragana, katakana);
sb.Append("From file :\n");
fs = new FileStream("japan.txt", FileMode.Open);
StreamReader sr = new StreamReader(fs, encJ);
string line;
while((line = sr.ReadLine())!=null) sb.Append(line + "\n");
sr.Close();
fs.Close();
I viewed 'sb.ToString()' in a richedit text box. The results
were as expected.

I tried the code you wrote below and created the japan.txt file.
My question,
When the file is in Shift-JIS format, and if we open it in MS Word 2K / Word
Pad, does it throw
a window saying that "This file has Shift-Jis encoding blah , blah ... ?".
( i think it does)
When i open Japan.txt, i do not get that encoding type window (does it means
MS Word is treating it as ascii ?).
Can you verify and let me know if you got that window?
Or am i not correct in assuming that ? (When i created UTF-8 files and tried
opening with word, i got that window)

Are you sure? I have no original file, so I can't test this.

There is no encoding information stored in the file. So it is
handled like every other txt file with the windows.default
codepage.
> Can you verify and let me know if you got that window?
I don't get that window, but I don't have expected one.
> Or am i not correct in assuming that ? (When i created

When you use a utf-8 coded file (or utf-7 or utf-16), the first
bytes in the file indicate the encoding format. This information
is automatically written to the file by the StreamWriter class.
Because of this information, every editor you are opening the
file with, knows the right encoding format(and a window pops up).
But this class doesn't write any encoding information to the
file if shift-jis is used. I don't know if this is right or not.
You have to look at a original shift-jis encoded file, to decide
if header bytes are used (needed?).
Till Meyer

that window.
I think you are correct about the initial byte. StreamWriter class writes if
it is utf-8 encoding but not Shift-Jis.
Maybe if i use FileStream class and write the initial byte myself, it will
interpret the file as Shift-Jis. I am not sure if this will work though.
(Please let me know if you need a smaple Shift-Jis for testing. I can email
it)

check "confirm conversion at Open". When asked about the file type, select
"Encoded Text File" and you will get the dialog about encoding.
Otherwise the file is treated as a text file using the default system
encoding (1252 if you are on a US system).

then add add the below codes, it shall work.
Encoding.RegisterProvider(CodePagesEncodingProvider.Instance);
Encoding enc = Encoding.GetEncoding("Shift-JIS");
