为什么非ascii字符显示为怪异的符号？ [英] Why non-ascii chars are displayed as weird symbols?

问题描述

我在这里有两种情况：

我的数据库包含很多我想要获取的信息，其中一些信息是名称，其中包含非ascii字符如 UweRülke

- 旧解决方案效果不错：
< BR>
我从数据库中获取数据，并直接从 VB 填充页面，同时循环。在这种情况下，所有字符都能正确显示 UweRülke

- 无法正常工作的新解决方案正确：


VB的 while 循环不会直接将数据扔到页面，而是在一个JS字符串中通过不时地调用数据库来提高性能）。但是当我使用存储在JS变量中的信息时，我得到了如下所示： UweR lke。

在这两种情况下，页面的编码为：

 < meta http-equiv =Content-Typecontent =text / html ; charset = iso-8859-1> 
  

我在哪里出错了？

编辑

这是用于从数据库获取js Strings

我使用 AJAX LOAD 从 ISEquery 来构建一个特定的请求并从数据库中查询它。它用于以 excel 文件或普通 HTML 的形式获取数据。

然后神奇的事情发生了，字符被误解了，我在 exctractFields 函数

  $（< div>< / div> ）.load（ISEquery.asp？isExcel = 0&+ info，function（）{
 //将字段提取到数组中
 var rows =; 
 var options =; 
 $（this）.children（）。each（function（index）{
 var fieldsArray = exctractFields（$（this）.html（））; 
 rows + = createISELine（fieldsArray）; 
 options + = createISELine_ComboBox（fieldsArray）; 
}）; 
}）; 
  

解决方案

感谢Aaron Digulla的answer ，我跟踪了从服务器到页面的字符串，发现它在 AJAX LOAD ，所以我找到了解决我的问题的答案。尽管我必须使用 charset =iso-8859-1来工作，而不是 charset =UTF-8


所以最终的答案是：
-Encoding在HTML页面中：

 < meta http-equiv =Content-Typecontent =text / html;字符集= ISO-8859-1 > 
  

- 编写Ajax数据：

<$ p $ {$ b $''beforeSend'：function（xhr）{
xhr.overrideMimeType（'text / html; charset = iso-8859-1'）; $ p $ $ .ajaxSetup
}，
}）;


现在字符显示正确。
感谢你们的帮助。

I have 2 cases here:

My Database contains lots of info which I want to fetch to the page, some of these info are name which contain non-ascii chars like Uwe Rülke

- Old solution which works well:

I fetch the data from DB and populate the page directly from a VB while loop. In this case all the chars are displaying correctly Uwe Rülke

- New solution which doesn't work properly:

The VB's While loop doesn't throw the data directly to the page, rather in a JS strings (to enhance performance by not calling DB each now and then). but when I use the info stored in the JS variables I got something like this: Uwe R�lke.

In both cases the page's encoding is :

<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">

Where did I go wrong ?

EDIT

This is the code used to Fetch (from DB) then save to js Strings.

I'm using AJAX LOAD from a page called ISEquery to build a specific request and query it from DB. It is used to either fetch data as an excel file or as plain HTML. At this point the chars are well represented.

Then the magic happens, and the chars get mis-represented, I checked it in the exctractFields function

$("<div></div>").load("ISEquery.asp?isExcel=0&" + info, function(){
                            // Extracting the fields into an array
                            var rows = "";
                            var options = "";
                            $(this).children().each(function(index){
                                var fieldsArray = exctractFields($(this).html());
                                rows += createISELine(fieldsArray);
                                options += createISELine_ComboBox(fieldsArray);
                            });
                        });

解决方案

Thanks to Aaron Digulla's answer, I followed the string from server to the page and found that it is gets misrepresented after the AJAX LOAD, so I found this answer which resolved my problem. Although I had to use the charset="iso-8859-1" for it to work rather than charset="UTF-8".

So the final answer is:

-Encoding in the HTML page:

<meta http-equiv="Content-Type" content="text/html"; charset="iso-8859-1">

-Encoding the Ajax data:

 $.ajaxSetup({
          'beforeSend' : function(xhr) {
           xhr.overrideMimeType('text/html; charset=iso-8859-1');
        },
    });

And now chars are displayed correctly. Thanx for your help guys..
