Html_entity_decode 或 encode or decode

Hello

I have import with API an old wordpress website. All is fine now. But when I edit some post I can see html code ans not the real characters :
From
culture "projets et accompagnement"
To
"culture "projets et accompagnement"

How I can force change it into all post ?
rake posts:remap ? An existing regex ? An feature or plugin ?

Thank you if you have any idea.

有一个 rake 任务可以替换所有帖子中的文本,并且还可以只针对包含特定文本的帖子,这样您就不会盲目地处理每个帖子。
