was initiated by city councillor Djalma Pastorello, of the PSDB. 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. The adjustment would therefore rationalise any search for the city in search engines, since Foz do Iguaçu's is more widely known for the falls, which are known as the Iguassu Falls. Djalma Pastorello felt that tourism to the city of Foz do Iguaçu would be improved greatly by a clarification of its association with the now-famous Iguassu Falls. However, he estimated that 70% of the city's population were against the name change because the local media anticipated the change and presented it in a distorted way, so that locals were unable to see that the intention was to benefit the population. Literature The region that today is part of Foz do Iguaçu, is described by Álvar Núñez Cabeza de Vaca in his diary that narrates the very experience at the beginning of the European colonization in the Americas. In contemporary literature one of the city's neighborhoods appears in a subjective way in the work of the writer Leonid R. Bózio, who reports in the book Tempos Sombrios, from the series Autofagia, local mysticism through the figure of Pombero, creature of the Guarani Mythology. Demographics The city has a population of approximately 265,000, whilst the Tríplice Fronteira (Tri Frontier) region (Ciudad del Este, Hernandarias, Puerto Iguazú and the rural areas included within those municipalities) has a population of 820,000. The city's population is heterogeneous, with many immigrant communities, such as: Arabs, Chinese, Germans, Italians, Paraguayans, Argentines, French, Swedes, Portuguese and Ukrainians. The residents are predominantly Roman Catholic but there is a relatively large minority of Muslims and Buddhists. The city has a large mosque and a Buddhist temple. Fenartec is an annual event held in May to commemorate the city's multicultural diversity.
