Describe the bug

Hello 😁 !

If I put this bunch of code

{{ sentenceCase('bon état')}}
{{ sentenceCase('bon etat')}}
{{ camelCase('bon état')}}

it output me

Bon tat
Bon etat
bonEtat

the é char is truncated. Same for the àchar. I don't have the time now to test with other chars and changing case helpers :-/

Have a good day and thanks for your work 😃 !

I've understand some hours after creating this issue, that's a bug relative to Poppins

I've created a PR for this #41
So closing this issue
