感谢，感谢，专门写了个油猴脚本

function replaceText(node) {
        if (node.nodeType === Node.TEXT_NODE) {
            node.textContent = node.textContent.replace(/�/g, '里');
        } else {
            for (let child of node.childNodes) {
                replaceText(child);
            }
        }
    }
   
    replaceText(document.body);
