Can't you just use nvarchar and ntext fields? I don't think you need to do anything differently in VB, as long as the SQL column type supports unicode (the ones that start with "n").

  Actually i already do something about it and now i wish to know is the way i doing thing is correct.

My Objective : to store the information(especially chinese character) in SQL Server 2000 as UNICODE(using UTF8 format)

Now, i have manage to store the data inside SQL Server 2000 as something similar as below

Field Name : CustName
Data Type : nvarchar
Length : 4000
Data : n233n131n145n229n136n169n230n152n142

What i do is i take the data that user input and convert it to something like this


then i store in database

when retrieve, i convert it back to the character or string that as the user input early

is this the correct way of doing it? or else?

coz i found that this way will take up alot of storing storega than usual

Azure has a changed a lot since it was originally introduce by adding new services and features. Do you know everything you need to about Azure? This course will teach you about the Azure App Service, monitoring and application insights, DevOps, and Team Services.

I'm curious, what happens if you just try storing the actual characters into an nvarchar field? Does it break or what happens? I was under the impression that nvarchar fields could store that kind of information without any conversion.
