Actually, singular "they" predates generic "he" by several centuries. Generic "he" was an 18th-19th century invention.
"Mankind" to refer to all humans.
"All men are created equal" to refer to all humans.
"No one shall be arbitrarily deprived of his nationality nor denied the right to change his nationality" refers to all humans.
More recently as other comments have pointed out, singular "they/their" has become more accepted. "No one shall be arbitrarily deprived of their nationality nor denied the right to change their nationality".
