Why can't I insert special characters (smilies) through the Django admin?

Question

Django

Hello!
why can't I insert special characters (smilies) through the Django admin? I want to insert
something like this into the title of the page (well, or into the content, through vizivig
)
to register.)
if inserted through vizivig, then everything is displayed in it, but when saved, it gives a 500 error and question marks (????) appear in the text instead of this special character
. Moreover, if you insert it into the html file of the template, then everything is displayed normally.
