What Unicode encodings does Unicode NSIS support?
Unicode NSIS supports UTF-16LE, the Windows default, and as of 2.42.3, it supports UTF-8. UTF-16LE requires a BOM in the front of the file. UTF-8 does not require a BOM and Unicode NSIS will read UTF-8 files with or without a BOM. Notepad.exe, for example, will add a BOM to UTF-8 files but most Unix tools will not unless explicitly told to. In any event, all the NSI, NSH files should be in some Unicode encoding supported by Unicode NSIS. The license file should also be either an RTF file, or a Unicode text file (UTF-16LE or UTF-8).
