We all know that ACCESS is a close partner of ASP. Because two of the simplest things always create sparks when they come together. However, when our filtering is not strict, Japanese characters often appear. At this time, Japanese overflow will occur after searching. At this time, the idea we can usually think of is to find an exe program to solve this problem. I originally wrote such a similar program in C#.
You should be able to find the one I wrote before on Google. I won’t say any more.
Then one day, I found that ASP could do it. I really felt like shit at the time.
However, this method of ASP is very bad. It is easy to cause system crash (if the database is large).
So just writing here. It can be regarded as a starting point.
'Let me explain it below:

Err.Clear
Dim objRS,i
Set objRS=Server.CreateObject(ADODB.Recordset)
objRS.CursorType = adOpenKeyset
objRS.LockType = adLockReadOnly
objRS.ActiveConnection=objConn
objRS.Source=SELECT * FROM [blog_Comment]
objRS.Open()
If (Not objRS.bof) And (Not objRS.eof) Then
For i=1 to objRS.RecordCount
'Traverse and see if there is any Japanese text. If so, it will overflow. Just search for anything. It doesn’t matter what you search for. Because it is traversing ACCESS, as long as the pointer moves to Japanese, it will overflow.
objConn.Execute(SELECT * FROM [blog_Comment] WHERE comm_ID=&objRS(comm_ID)& AND [comm_Content] LIKE '%URL%')
If Err.Number=-2147217900 Then
'Because on err continues, the overflow error code is found here. This was debugged by myself, and it was not actually found from somewhere.
objConn.Execute(UPDATE [blog_Comment] SET [comm_Content]='&FilterSQL(Japan2Html(objRS(comm_Content)))&',[comm_Author]='&FilterSQL(Japan2Dc9CnHtml(objRS(comm_Author)))&' WHERE comm_ID=&objRS(comm_ID )& )
'This is to replace the Japanese text. Isn't the idea very clever? kindness. However, if the database becomes huge, repeated overflow will cause problems. Memory babies will cry.

By the way, my blog has been hacked repeatedly recently, which makes me very depressed. Because it is done by Arabs or Israelis, I cannot communicate.
I still can't figure out how they did it.
Really depressing.
alright.
in the following days. I will post some more technical posts. I suddenly felt that this seat was very precious.
