feat: get windows building with the UNICODE forced by using Qt refactor: remove ARCHString use QString to convert to / from utf8 build: (arch) link to common build: (base) link to arch build: (io) Link to common build: (client) link to common build: (server) link to common fix: Append to log file instead of creating a new one each log line refactor: Trim cipher description for neater log output fix: Update log messages to use wide string format for Unicode support fix: Correct event creation to use wide string for Unicode compatibility refactor: Use QStringDecoder for UTF-8 handling on Windows Daemon child process fix: Use correct wide type for Win32 consts
