Did editng the page involve cut/paste? Most likely then it's the same issue as in .as in https://phabricator.wikimedia.org/T76916 - Pasting an external link adds a ☀
"position your cursor at the end of the line that has and paste the copied word from TextEdit(Notepad)
The pasted word will be on the next line with ☀ char."
On the page https://en.wikipedia.org/wiki/Parvaneh_Eskandari_Forouhar I did not see ☀ and there was no - the page was cleaned of ☀ by the end of editing?
