Charset, utf-8, OJS 3.0.20

Maybe your default connection in XAMPP is utf8? With this combination: locale en_US client_charset utf-8 connection_charset Off database_charset Off charset_normalization Off mysql default connection: latin1 ojs table encodings: utf8 You might end up with a situation where everything seems fine when looking from OJS, but the utf8 characters are actually saved as latin1, like this: Ô ß è So I would check the server default connection setting first.
