notes field wrong codepage

Hi there,

We just set up the booking pages on 2 users in our organization, and when a booker uses the Greek language to write the Notes field, we receive the characters in web format: 


ΑΒΓΔΕΖΗΘΙΚΛΜΝΞΟΠΡΣΤΥΦΧΨΩ
αβγδεζηικλμνξοπρστυφχψω


Here is my booking page: Book time with George Tatsis: book a VIP session   

We also tested another user with Greek settings and the same behaviour regarding the Notes field content. 

I tried to find the bookings with me settings, I ended up to Office 365 settings where everything looks good.

Any ideas? 

I appreciate your support,

George
