If you enter a city, Enigma automatically finds the coordinates. However, this did not work well for cities that used accented characters. If you searched for Malaga in Spain, it would not find anything because the name was spelled Málaga.
In release 0.8.2 Enigma only uses plain characters, so it is easier to find the correct city.
Also, if you selected a line with an astronomical event in PreNatal, the text was difficult to read. In the new version, the text contrasts better with the background.
