The purpose of the adjustment to the city name was to return the spelling to the original form, as at the foundation of the city in 1914. The change occurred due language reforms of 1945, which changed the orthography of Brazilian Portuguese. However, existing proper names were not obliged to change. Another reason for the proposed adjustment back to the original was that 146 of the 198 member countries of the United Nations do not have the "ç" character in their alphabets.
