Explanation
Change Character Encoding to UTF-8 and Select Unicode Output are two settings that could solve this issue.
Character Encoding is a setting that determines how characters are encoded and decoded when importing or exporting data in Marketing Cloud. UTF-8 is a type of character encoding that supports all characters in the Unicode standard, including accented characters. Unicode Output is a setting that enables the output file to be encoded in UTF-8 format when exporting data from Marketing Cloud. By changing Character Encoding to UTF-8 and selecting Unicode Output, the admin can ensure that accented characters are displayed correctly in the extracted file.
