Hi Robert,

I am not aware of any outstanding issues regarding custom delimiters in Vue.js 3.x.

The documentation of Vue.js 3.x tells us to do something like this if we wanted to use custom delimiters:

```

Vue.createApp({

// Delimiters changed to ES6 template string style

delimiters: ['${', '}']

})

```

This is similar to how I defined custom delimiters in this article:

```

delimiters: ['[[', ']]']

```

Also, it would be really helpful if you provide your code so that I can help on debugging your issue easier.
