Korean characters replaced by ??

We are using MS SQL 2012 (Azure). When our web application saves text into an nvarchar field (Max) if the user has a Korean keyboard the Korean characters are replaced by question marks.   ???

Any idea how to prevent this in order to accept Korean characters?

What is the charset used by both your web server and your database? In order to preserve those characters, they should both be at least "UTF-8".

If they are "US-ASCII" or "ISO-8859-1", you'll need to update the charset.

We use classic ASP. Where can I check both ?
Jan LouwerensSoftware EngineerCommented:
For your web pages, just look at the source, and in the head you should have a tag similar to:
<meta http-equiv="content-type" content="text/html; charset=UTF-8" />

Open in new window


As for the database, you'd probably need to contact your DBA to determine what charset it was set up with.

We do use UTF for the ASP pages. Ill ask the DBA tomorrow about the Database. I think its set to Latin. Could that be the issue?
Jan LouwerensSoftware EngineerCommented:
Yes, that very well could be the issue.

The charset used by the database most likely does not support Korean characters.

After checking we figured that the field had to be changed to nvarchar AND the insert into the table needed to have N'  before the content.
This allowed us to save the content in Korean characters.
