Special Characters Not Displaying

  • Hi there,

    A client’s website shows a ? instead of special characters like accents é è à. Thanks to the Wayback machine, I see that it was working fine in December 2022, and now all special characters are showing a question mark.

    We are using an outdated version of Gateway because the updates break the site design.

    How can I update the charset in the theme files? I see the current charset value is set with this snippet:

    <meta charset="<?php bloginfo( 'charset' ); ?>">

    I tried changing it to:

    <meta charset="ISO-8859-1">

    Without success.

    Please advise. Thanks!
