Question

ASP.NET callback to encoded URL with UTF characters fails on IE

Answer 1

A:

This article may help.

From the article that explains what IE does:

What do web browsers do if they don't find any Content-Type, either in the http headers or the meta tag? Internet Explorer actually does something quite interesting: it tries to guess, based on the frequency in which various bytes appear in typical text in typical encodings of various languages, what language and encoding was used. Because the various old 8 bit code pages tended to put their national letters in different ranges between 128 and 255, and because every human language has a different characteristic histogram of letter usage, this actually has a chance of working.

Make sure that the first meta tag in the head section of the web page contains the following:

<html>
  <head>
    <meta http-equiv="Content-Type" content="text/html; charset=utf-8">

Thank you for your answer David.I am quite aware about Unicode and that article written by Joel. Of course, I have proper meta tag. Just to be sure I moved it to be first above all and this didn't help.In general, site navigation as well as postbacks works well. The problem is only with AJAX callbacks made by ASP.NET built-in function WebForm_DoCallback. It seems that it has bug which results in incorrect handling of encoded URLs. I need to find some workaround but it looks pretty difficult for me because it all looks as "black box" behind my code.
