Problem using Mysql++ query with utf8

[Joy Zhang]

I am using Mysql++ to access a DB where queries need to contain UTF8 characters.
Mysql server is running on Linux Fedora and the DB has been set with UTF8 collation.
I have tested the query using both php and running directly on phpmyadmin and it worked out fine.
However, using the C++ code listed below the DB always record the field in ASCII form as "Nürnberger".

I am really frustrated by this.
I have been google all day but it seems like no one has this problem before.
Is this a problem with mysql++ or something I did wrong?

Appreciate your help.

mysqlpp::Query query = conn.query();
query<<"insert into chinese_english (UserName) values ('Nürnberger')";
query.execute();
