today i had a problem with filenames. I named my files with the camera temperature using the degree symbol °, e.g. NGC281_-10°C-Offset100-Gain177.fits. I store the files on my linux fileserver via samba.
I can easily open the files from the network drive directly but trying to convert them fails. After i have renamed the files and replaced the ° by “Grad” (german word for degree) it works. Looks like accessing the files with the open function and during conversion works different. OS is Windows 10, Siril 1.0.6 last official version.
