Jolla is in the process of open sourcing components. See this forum post from today .

Some components are proprietary. See https://docs.sailfishos.org/Develop/Open_Source/ .

Works well enough for me, it’s comparable to my Android phones. But I’m not a heavy GPS user.

I’m using Sailfish OS on a Jolla C2 phone. The OS is great, very good native software and it also runs Android apps.

Can’t confirm that. In the 90s encodings were a nightmare. ISO-8859-1, ISO-8859-15, CP1252, IBM850, … If you tried to build a website with an upload form, you’d get the most bizarre encodings and there was no way to reliably distinguish them. I’m not an English native, my world is full of umlauts and s-z ligatures. Things got A LOT better in the last years, thanks to Unicode encodings.

These errors were much more common before Unicode encodings were in broad use. Unicode pretty much solved this.
