I want to do xss protect processing on the backend(used this library https://github.com/naver/lucy-xss-filter). But it has a problem. My front is made with vue.js and I am using tiptap as an editor. Problem is This editor automatically convert characters like ?, &, /, <, >. So, when I convert in the backend, it is converted twice. As a policy issue, the conversion must be done in the backend. Is there a way to get the original unconverted string from the tiptap editor?

vue : 2.6.11 tiptap-vuetify : 2.24.0
