First of all great component

.
I don't have problem with translation of component it self because I can understand every single option in component.
I need help with already made form. My language is Polish one and on a front-end I can't see Polish special letters (like ś,ć,ź etc).
I even try to change component language but it hasn't change anything. It's component translation and it doesn't chage anything.
Whant I'm doing wrong. Please help me!
