Hidden Prompt Injections with Anthropic Claude

A few weeks ago while waiting at the airport lounge I was wondering how other Chatbots, besides ChatGPT, handle hidden Unicode Tags code points.
A quick reminder: Unicode Tags code points are invisible in UI elements, but ChatGPT was able to interpret them and follow hidden instructions. Riley Goodside discovered it.
What about Anthropic Claude? While waiting for a flight I figured to look at Anthropic Claude. Turns out it has the same issue as ChatGPT had.
