Decode S-JIS String To UTF-8?

Jan 7, 2011

I am working on a Japanese File and I have no knowledge of the language. The file is encoded in S-JIS. Now, I am supposed to convert the contents into UTF-8 so that the content looks like Japanese. And here I am completely blank. I tried the following code that I found somewhere on Internet but no luck:

byte[] arrByte = Encoding.UTF8.GetBytes(arrActualData[x]);
string str = ASCIIEncoding.ASCII.GetString(arrByte);

.NET Is Unable To Decode String When Java Can "Hi%E1" ?

Feb 18, 2010

My problem is with .Net Http/Uri libraries not being able to decode or unescape this character sequence: "Hi%E1". Neither Uri.UnescapeDataString nor HttpUtility.UrlDecode can do it.

Although I have a solution to get around this problem ( http://stackoverflow.com/questions/1221849/url-decoding-confusion ) I would like to understand why it is failing.

The 1st test here throws an exception! The second just fails.

Assert.That(Uri.UnescapeDataString("Hi%E1"), Is.EqualTo("Hiá"));
HttpUtility.UrlDecode("Hi%E1").ShouldBe("Hiá");

There is nothing in the docs to indicate that UnescapeDataString or UrlDecode are restricted to character sets or any reason why these tests would fail. However, from testing, it would appear that HttpUtility assumes UTF-8 (or some other) encoding.

The Java equivalent works! Probably because it allows an encoding to be set.

URLDecoder.decode("Hi%E1","windows-1252"); // this works btw, ie passes tests

Which looks like a very sensible move considering the .Net work-around (see URL above)

Are the .Net implementations of these methods just crap and .Net devs just have to write their own - or am I missing something?

BTW Everything I know of in IIS set to UTF-8, and Chinese/Japanese characters show fine, so I don't yet know how it could it be that this URI consists of windows-1252 encoded characters. If I could fix the URI to contain UTF-8 encoding, that would be a better way of fixing this.

Edit I'd misunderstood what was happening here.. there is a POST send, then receive back a result, then the URL string which I'm seeing here is part of the the query string... so I can't decode what this really is, as it is encoded by the payment gateway people and not me.

MVC :: HttpUtility.Decode Does Not Work In TextBox Or TextArea?

Jul 17, 2010

I am trying to render html encoded string that is stored in SQL Server into human readable form. The HttpUtility.Decode does not decode the text that is rendered in between the open tag and closing tag of any input tag (ie. TextBox or TextArea or Select) in my ASPX page. However, HttpUtility.Decode works fine if the text is not in an input tag. The following is my test code. For example, the value of AdmitDX field in database is "Someone's comment" which is "Someone's comment" when decoded. The first two code nuggets <%%> will show as "Someone's comment" and the thrid code nugget will show "Someone's comment".


<%= Html.TextArea("AdmitDX", HttpUtility.HtmlDecode(thisTransfer.AdmitDX))%>
<%= Html.TextBox("AdmitDX", HttpUtility.HtmlDecode(thisTransfer.AdmitDX)) %>

Test = <%= HttpUtility.HtmlDecode(thisTransfer.AdmitDX) %>

Jquery - Allow User To POST Html String To A HttpHandler?

Feb 11, 2011

I am writing a content management system using JQuery.ajax & C#. The JQuery calls an httpHandler and POSTS the html from an html editor JQuery plugin.

I get an error in the handler about unsafe content (html basically) but I dont want turn off validation for the whole page, just the handler (the handler is part of a web control not the page).

So, is it possible to turn the validation off just for one handler? Or do I need to encode the html on the client?

In the end I went for the encoding on the client at Javascript/JQuery HTML Encoding
