I am trying to export data from my database (UTF-8) to CSV which is to be opened on MS Excel (Latin 3). For that I am using

$data[$keyLine][$keyField] = utf8_decode(html_entity_decode($curField, ENT_QUOTES, "UTF-8"));

The problem is that my data is in French, and includes words such as cœur. All data exported is looking fine except that composed character œ, where I am getting a question mark (cœur is converted to c?ur), how can I fix this?

Thanks in advance.
