asp.net - 字母变成 "ë"

Question

我有一个网站，还有几个文本框。如果用户填写包含字母“ë”的内容，那么它会变成:

ë

我怎样才能像这样将它存储在数据库中？
我的网站建立在 .NET 之上，而我使用 C# 语言。

ASP.Net(您的服务器端应用程序)和 SQL Server 都支持 Unicode。它们可以处理不同的语言和不同的字符集:

Internally, the code behind ASP.NET Web pages handles all string data as Unicode. You can set how the page encodes its response, which sets the CharSet attribute on the Content-Type part of the HTTP header. This enables browsers to determine the encoding without a meta tag or having to deduce the correct encoding from the content. You can also set how the page interprets information that is sent in a request.

Finally, you can set how ASP.NET interprets the content of the page itself — in other words, the encoding of the physical .aspx file on disk. If you set the file encoding, all ASP pages must use that encoding. Notepad.exe can save files that are encoded in the current system ANSI codepage, in UTF-8, or in UTF-16 (also called Unicode). The ASP.NET runtime can distinguish between these three encodings. The encoding of the physical ASP.NET file must match the encoding that is specified in the file in the @ Page encoding attributes.
