If it can help someone, here is a small code to make a safe Text component (really improvable):

import {
  Text as UnsafeText
} from "@react-pdf/renderer";

function safeText(text) {
  const str = text
    ? Array.isArray(text) ? "" + text.join("") : "" + text
    : "";
  return str
    .replace(/\n\n/gim, "\n \n")
    .replace(/\n\n/gim, "\n \n")
    .replace(/ $/, " ");
}

function toSafeText(Component) {
  return function({ children, ...props }) {
    return <Component {...props} children={safeText(children)} />;
  };
}

const Text = toSafeText(UnsafeText);
