Encode/Decode Chinese Characters?
Nov 10, 2011
I have a call to Server.URLEncode(string) from an old asp file that stores user input into a table. In this case it was a string of Chinese charters.
The actual data is :
%E8%B0%B7%E6%AD%8C%E7%9A%84%E5%89%8D%E6%99%AF%E9%BA%A6%E5%85%8B%E6%96%AF%E9%9F%A6
I rewrote the code to vb.Net and after I get the data from the table, I call
HttpContext.Current.Server.UrlDecode(string) to decode the string, add it existing mark up for an email and send it on its way.
Note that with Visual Studio i can see the HTML markup as it appears in the email, and ALL of the Chinese data is EXACTLY as I would expect it.
When the emial is received i get "???????????" characters where there should be the Chinese characters.
What I do not understand:
What Server.URLEncode actually encodes the data to. It appears to be HEX.
What the array of "?" means in outlook or any other email system that opens it, I assume it means "Hey i cant convert this stuff, so here is a question mark for kicks, good luck."

I have the following code:
Dim lStatementText As String
Dim lStatementString As New System.Text.StringBuilder
lStatementString.Append(RndRes.Forms.txt_request)
lStatementString.Append(" ")
lStatementString.Append("<b><a>")
[Code]...
Where Request.ID, Request.Description and also RndRes.Forms.txt_* are all strings. I want to display the string I build up here in a Infragistics FormattedLinkLabel. The problem is that if any of the strigs from the Request class contains a HTML character, the label is not displayed properly and the HTML encoding is broken.I need to find a function that masks the HTML codes.

I have to provide a client with a method to retrieve data from an Audiometer. The equipment is discontinued, but they have six of these and are used every work day. Using port monitoring and the DUMP command on the peripheral I was able to read the data and save to file. Now my challenge is decoding each line. It appears that only a section of the string is not in plain values.I added the pipe separators for clarity. I have determined those columns are: EMPID | DateTime | TechID | Results | ResultType = Test.[code]

I need to validate a basic authorization header that is being sent to my HttpListener in VB.NET. I'm grabbing the header like so (feel free to point out better ways to do this as well):
EncodedAuth = Context.Request.Headers.GetValues("Authorization")(1)
Now how do I decode them? I understand the theory but I can't seem to find the right code.

I have to make a virtual keyboard with my application which needs to input Chinese characters.
I can change the input language to Chinese, but cannot input Chinese coding as normal keyboard does...(I am using SendKeys.Send("A") as if I am pressing the "A" key on the keyboard, but the focus is on my virtual keyboard (another form other than the form of editing).)
any solution which I can get the virtual keyboard and the main task in the same application?

I'd like to build a simple json looking like this: {"Count" : "55", "total" : "125,55"}On my vb method i'm doing this to encode it:Dim json As String = "{""Count"" : "" " & intCount & " "", ""total"" : "" " & intTotal & " "" }"But I think Im missing something to escape the quotes, when my browser received it, it looks like this: {"d":"{"Count" : " 5 ", "total" : " 55 " }"}making it unreadable for jQuery.

I am creating xml files that contain chinese posts and it seemed to be working but I started getting an error:
This page contains the following errors:
error on line 4165 at column 25: Input is not proper UTF-8, indicate encoding ! Bytes: 0x0B 0xC3 0xA5 0xC2 Below is a rendering of the page up to the first error.
When trying to open some of the resulting files.The line it references contains chinese characters and this occurs only in some situations and my guess is that the text is sometimes containing some characters that throw it off. How can I ensure that the text for that field will always be properly encoded? I don't even understand why the issue yet.
Public Shared xwriter As XmlTextWriter = New XmlTextWriter(xmlfile, Encoding.UTF8)
I make sure the xmltextwriter is properly declared.
EDIT:
The issue is that I use vb.net and apparantly it encodes everything in utf-16 so I assume this is fine. The problem is that the text I am receiving is probably double encoded or incorrectly encoded and I need to clean it before using it; so that my xml is valid.
EDIT:
so if I need to fix my data, my question is how can I detect what encoding is used for a specific text and how do I convert into utf8 format that can be viewed in an xml file and make the file valid.

Is there a way to detect a Chinese character in a string which is build like this:
dim test as string = "letters 中國的"
Now I want to substring only the Chinese characters. But my code is database driven, so I can't substring it, because the length is always different. So is there a way I can split the string, from the moment I detect a Chinese character?
