Dear all
I have a problem with the page coding and I don;t know where to solve it.
I have two webpages with the same configuration (or it should be the same).
The problem is that I see in the source uncoded letter "ó" what causes problems when posting to socials. Both websites have UFT-8 coding, and in one page source I see:
"[...]dzięki której" and in the second I see ""[...]dzięki której".
Do you any hint where should I look for a coding settings or what K2/joomla setting should I compare?

thanks in advance,
best regards!

of course the problematic letter is ""&oa cute;" (without space)

thank you for help and suggestion. I will investiage that.
have a pleasant day!
best!
