Special characters when $model->save

There is a special character in the string $title = "Interview – BBC"

The special character is –

after $model->save()

the title in the table will become "Interview", not the whole string "Interview – BBC"

Yii model will cut the string if meet some special character

how to keep the whole string when save?

Some characters will become & # 22882;& # 20360;& # 21697; in the database

I’m not shure. I thunk depends of differents charset from database and page. I would try with utf-8 in both situations.
