Getting strange letters or text additions when publishing the copyright symbol. Also when I write - it’s - it changes completely. In elements it’s fine, even in Safari it shows okay only after publishing and downloaded at the server it’s wrong.
No, that’s a character encoding problem, not a font problem. It looks like multi-byte UTF-8 characters (i.e. the copyright symbol and a smart quote) that are rendering correctly in Elements and Safari in preview, but not when published.
If the server is Apache try adding the following to your .htaccess file:
AddDefaultCharset UTF-8
If not Apache consult the documentation for an equivalent setting.
