Error with contact form responses to Gmail

I have several contact forms in my squarespace site, the repsons of the forms goes(storage) to my Gmail inbox. 

In all of my forms there is from yesterday a error with scandinavian letters Å Ä and Ö. It worked before but now word that contains this letters are tranmitted wrongly to Gmail. 

For example, the word omgående in my contactform is "omgående" in the Gmail inbox where the form is stored. 

Anyone else got this problem? Very grateful for hints about solutions.
