Dear All,

Good Day

I am trying to convert a file which is generated on AS400 with codepage 00420 (arabic & English data combination) with no success. But using the same code( and changing 20420 to 708) I am able to convert a file from codepage ASMO 708 to windows based file and it is perfect. The following is the code I tried. i used 20420 codepage which is the nearest match for 00420. but no luck.

//Open file for reading and set encoding to 20420
StreamReader sr = new StreamReader((System.IO.Stream)File.OpenRead(strInFile ), Encoding.GetEncoding(20420));

//Openfile to write and set encoding to default

StreamWriter sw = new StreamWriter(strOutFile, false, Encoding.Default);

and I read the input file line by line and then write each line to the output file
//Read line
Line = sr.ReadLine();

//Loop logic here and then write to file

//Write line
sw.WriteLine(Line );

I verfied in windows regional settings to make sure that codepage 20420 is checked. Still I am not able to convert the file. The output is full of questions marks, which i belive is because it didnt recognize the character.

Anyone please help me to solve this issue.

Thanks in advance
Ram

Are you sure that all the characters in the file are available in
Encoding.Default?

I would suggest you separate the reading part from the writing part -
read some data and then write out the Unicode values you've read, eg

foreach (char c in line)
{
Console.WriteLine ((int)c);
}

Then look on www.unicode.org to see whether those are correct.

When you've got the reading of the data sorted, you can then move onto
trying to write it correctly.
 
When you refer to Unicode Values i am confused. Is it because I am using 20420 encoding the string becomes unicode?

Now i am displaying the values, but which character mapping should i look in Unicode.org.

I am new to this codepage conversion stuff. If it is a basic question please excuse me.

Thanks & Regards

Strings in .NET are *always* in Unicode.

Look in http://www.unicode.org/charts and find the chart with the right
region of characters in. For instance, if you saw character 0x0785
you'd look down the list until you found
http://www.unicode.org/charts/PDF/U0780.pdf - unfortunately you
basically need to look at where the links go to work out which one to
follow.

I should have said before - it'll be easier for you if you print out
the values in hex, eg

Console.WriteLine ("{0:x}", (int)c);

It's hard to say whether it's a basic question or not at the moment :)

See http://www.pobox.com/~skeet/csharp/unicode.html for more
information though.
