then I have some unspecified character before "°C" as on screenshot below:

Hi, This is most possibly because the string encoding used to edit/save the file does not match with the one specified on the first line of the csv. I am not sure what is the standard encoding used in your area but such kind of things would happen for example if you save the file as UTF8 but then you specify # %encoding WindowsLatin1 (or nothing) on top of the csv.
Still I am partially intrigued on your particular case because I see other diacritic characters displaying just fine, and also the ºC is correctly displayed after all (except for the leading Â of course). Maybe there is some extraneous character before the ºC that does not display on the editor?.
In any case please first make sure that the string encoding used by your text editor matches the one specified on top of the csv, and then let me know. Thanks
