There are a lot of articles about this on the net:
But suffice to say this. When you save characters from a form postback the characters ***will*** be encoded. If you do not specify an encoding it will be determined for you.
This can be very confusing!!!
Chinese characters may appear to look OK in ASP but not in ASP.NET
So to stop problems, always declare your encodings! Typically we use utf-8.
In ASP, do this:
@CodePage = 65001 Option Explicit Session.CodePage = 65001 Response.CodePage = 65001 Response.CharSet = "utf-8"
When saving SQL directly, make sure the characters get saved in nvarchar, ntext etc
Declare the encoding in HTML as well:
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
In ASP.NET, add this to web.config:
globalization requestEncoding="utf-8" responseEncoding="utf-8" fileEncoding="utf-8"
