> When you do a form submit (POST or GET of data to the server), the browser encodes the characters being sent using the character encoding that the page uses. In your case, from the examples you sent, this encoding is Unicode UTF-8. UTF-8 is a multibyte encoding of Unicode in which non-ASCII characters take two or more bytes. In this case, the German accented characters each take two bytes.
> When the server receives the data, it decodes the original bytes sent by the browser. The problem is: what encoding should be used to interpret the bytes? For historical reasons, most Web servers (include J2EE, .NET, Apache/Tomcat, etc.) default to using ISO-8859-1 (Latin-1), a single byte Western European encoding. This is what is happening in your case: each UTF-8 byte is being treated as a single character, leading to the corruption you are experiencing. You can see that each German character is interpreted as a sequence of two bytes.
I and I'm sure many others have seen this problem too.
that web servers default to serving UTF-8 instead of ISO-8859-1. The W3C should really stipulate UTF-8 as the default.
In the case of Apache, it is trivial to change the configuration file to UTF-8 instead of ISO-8859-1 (I even remember that
it's around line 780 something
in the default configuration file distributed with Apache version 2.x), but I wish it was the
DEFAULT. In the case of IIS (the server used for serving the form which was highlighted as having the problem at the beginning
of this thread), I would assume that it would also not be difficult to set the configuration file, but I don't have first-hand
knowledge about how to do that. In any case, UTF-8 should be the default for IIS and all the other servers out there.
When I look at the rather long trail of emails in this thread -- all of this stuff about legacy character sets and what
browsers and servers are going to do -- or not do as the case may very well be -- with characters that are not defined in
legacy character sets -- I think to myself, "Well, come on! The answer for solving almost all of your problems is so obvious:
use Unicode and in particular, that very useful transformation format called UTF-8!" For European languages using Latin script,
that, on average, web pages are going to be a few bytes longer than they were before under ISO-8859-x -- but it's nothing
are all designed around UTF-8 today, it means that you'll have a lot less work to do tomorrow when (1) you or client decides
to go after some other global audience or market or (2) XML rules the world, or (3) both.
And then threads like this one will be just a thing of the past...
