Saving multilingual text inside SQL Server Advantages: In most of the sites you would have seen the user downloading a type of font and installing it in their Windows ŕ fonts folder. The users will be able to see the characters of that particular language only after this downloading is done. But if you as the site developer save the Unicode text that represents a language inside a table and display that content in the web page then there is no need of user downloading the font. Isn’t this a great advantage? (For ex: If you are creating a web page in Chinese language then the user would be forced to download some font files which would be approx 6MB.) Disadvantage: If you like to offer multiple language support to users of your website, it is most important to use the Unicode character strings, nchar, nvarchar, and ntext (where n stands for “National”), for all character data but the sad part is that it would take more storage space than the character strings. A small example Web page 1 Create an html page from where you can copy multilingual text from any site and paste it in a provision given in this page. Please note that I am not concentrating on any client side validations here. So it is your responsibility to add any client side validation according to your needs. <Html>
<Head>
<Meta http-equiv="Content-Type" content="text/html; charset=utf-8">
<Title>Saving Multilingual character into database</Title>
</Head>
<Body>
<h3 align="center">Copy multilingual text from any site and paste it inside
this textbox before pressing the submit button</h3>
<form name="frmInputDB" method="post" action="frmSaveandRetrieve.asp">
<table border=1 align="center">
<tr>
<td>Enter your text here :</td>
<td><input name="txtMultiLingual"></td></tr>
<tr>
<td colspan="2" align="center">
<input type=submit name="btnButton" value="Submit">
</td>
</tr>
</table>
<p><p>* Please note that no validation has been done in this page.
</form>
</Body>
</Html>
Did you note the change in the meta tags charset property? Yes you need to specify “utf-8” as your charset so that Unicode characters would be allowed in that page. If you try skipping that line while creating any multilingual web page you would get an error while saving that page. The error would read something like this “Some Unicode characters in the file cannot be represented in the current code page and were replaced by default character…….”. Web page 2 <Html>
<Head>
<META http-equiv="Content-Type" content="text/html; charset=utf-8">

<Body>

Dim DBConn,strConnection,sql,
strConnection="---Put your connection string here."
Set DBConn = Server.CreateObject("Adodb.Connection")
set Rs=server.CreateObject("ADODB.Recordset")
DBConn.Open(strConnection)
Strdescription = Request.Form("txtMultiLingual")

<td>Multi-Lingual Text</td>
</tr><%
while not rs.EOFResponse.Write ("<tr><td>")Response.Write Rs("id") & "</td><td>" & Rs(1) & "</td><tr>"rs.MoveNextwend%></table></Body>
</Html>If you try to insert data in some language, which isn’t the default language of the OS or SQL Server, then all the characters inserted into the database might be substituted. Since SQL Server 7.0 and 2000 support both Unicode and non-Unicode data types, they require you to use the "N" prefix in front of Unicode string literals (before the open quotes). Just remember: simply place that "N" prefix in front of the string literal you are using. This will allow your data to be inserted without being corrupted, and this would also be a faster process! A small DB structure CREATE TABLE UniTesting (id int IDENTITY (1, 1) NOT NULL ,
description nchar (100) NULL)
