BUG: Failed to execute 'btoa' on 'Window` due to some CSS from bootstrap 5 about cli HOT 4 CLOSED

@cgaube thanks for reporting this. This is happening because btoa doesn't support unicode characters, which bootstrap seems to be using. We're looking into this and will get back to you soon.

from cli.

Thanks @samarsault Looking forward to that

I did some testing around and removing the call to btoa seem to make everything work for me.
I must be missing some context but I am not sure why this data has to be base64 for it to work

let content = data;

from cli.

Are you using bootstrap with adoptedStylesheets? We use btoa to create a serialized resource at our server for an adoptedStylesheet, and the server expects a byte data buffer.

from cli.

We are using Lit to create web components and for styles they tell us to do this https://lit.dev/docs/components/styles/

I believe their css function does use adoptedStylesheet under the hood

Thank you
