wordpress sub-category ( lowercase letters + non-latin characters ) = 404

⚠️ Temporary workaround

sudo apt-get install nginx-extras

nginx.conf

https://stackoverflow.com/a/11170826/15497563

http {
    # Include the perl module
    perl_modules perl/lib;

    # Define this function
    perl_set $uri_uppercase 'sub {
        my $r = shift;
        my $uri = $r->uri;
        $uri = uc($uri);
        return $uri;
    }';
}

server {
    location ~ ^/(부모/자식a|부모/자식b|부모/자식c)(.*) {
        rewrite ^(.*)$ $scheme://$host$uri_uppercase;
    }
}

Every time you create a sub-category(lowercase letters + non-latin characters), you need to edit it…
