Release note: https://github.com/pulsar-edit/pulsar/releases/tag/v1.105.0 This Pulsar release was made from a Windows computer, the SHA256SUMS.txt file was encoded in UTF-16LE with BOM. Most of the work was enhancing the update script to handle this case. Also implemented the recommendation from SuperSandro2000: https://github.com/NixOS/nixpkgs/pull/226616#discussion_r1170658908
