Encoding problem classic ASP

Question

Hi!

have a problem with classic asp. The encoding gets wrong when I send data with XMLHttp.send. The response is an pdf file, but the “ÆØÅ” gets wrong, the “Ø” is read as “øy” for example. It’s like it’s a converting mistake from UTF-8 to ISO-8859-1, but it should be ISO-8859-1 now. I have <%@CODEPAGE="28591"%> at the top at the page and ISO-8859-1 as encoding in the xml file, I have checked the file so it’s valid ISO-8859-1. I don’t have access to the server I send this data to, but I fixed it in a VB6 program which use the same logic with:

aPostBody = StrConv(strBody, vbFromUnicode)

WinHttpReq.SetTimeouts 100000, 100000, 100000, 1000000

WinHttpReq.Send aPostBody

And in a C# program that also uses the same logic with

// ISO-8859-1

byte[] bytes = Encoding.GetEncoding(28591).GetBytes(data);

But in asp classic I could need some help to find a way to change the encoding on a string to ISO-8859-1…thanks for help!

Answer 1

Try:

Session.CodePage = 28591

There is some good information here, and I got the CodePage number here.

Answer 2

Thanks for the answer, I didn't work. I can't really see why not, but since I managed to change it in the two other version I guess there is a way to change it in classic ASP to.

Answer 3

Have you tried using Response.Charset and setting it like so:

<% Response.Charset="ISO-8859-1"%>

Answer 4

AFAIK this is a known problem with WinHttpReq / XMLHTTPRequest, hope someone proves me wrong.

Answer 5

Have you tried using the meta tag equivalent to what you are doing?

Example: Response.Write("")

Note: I use a "response.write" to paste spit out the charset, because Visual Studio will attempt to save the file with a different encoding if, for example, the charset is UTF-8.

Answer 6

Sorry, my example had HTML but was stripped out.

Answer 7

Also, please note that the default encoding returned by .NET will be UTF-8. If you want a different encoding type, you can do so in the web.config and/or handle it specifically with code.

Answer 8

Thanks for the answer! I couldn't get the response.write to work either. The problem is that this part of the solution is made in classic asp, so I don't have the libraries I wish I had from .net. The thing I’m trying to do is send a string to XMLHTTP.Send like this:

XMLHttp.send strBody

The strbody object will look like this:

strBody = "--Xu02=$" & vbCrLf & _ "Content-Disposition: form-data; name=file; filename=" & vbCrLf & _ "Content-type: file" & vbCrLf & vbCrLf & _ strXML & vbCrLf & _ "--Xu02=$--"

and I then get a PDF in return

The variable strXML is the xml I’m sending in, I write this to a file before the send request, so I could verify that it's up to the standard.

Answer 9

Check the enconding of the .ASP file and all the .ASP file included with #include

Once I have a problem when I create a new .ASP file in VS and was enconding in UTF-8. This file was included by others, and the file enconding "overwrites" all other enconding commands.

Answer 10

Eduardo is correct.

However, if that still is not the problem and since you are using XMLhttp.send, why don't you reference http://msdn.microsoft.com/en-us/library/ms763811(VS.85).aspx to set the charset for the request.

Answer 12

Thanks for all the answers! Nothing seems to work, but I think the problem might be on the server I send it to, I must have tried it all now... I will set up a test server so I can check what happens when I post to that. Thanks for help!

Hi, I have used this component both on ASP and Javascript, but on javascript I found the resolution for this issue here: http://squio.nl/blog/2006/06/27/xmlhttprequest-and-character-encoding/

bye!
