Buster >> Bullseye - Remote upgrade

These instructions can be used to upgrade Raspberry Pi OS from Buster to Bullseye with only an SSH connection (no physical access). Some addidional steps are performed to make sure that the Pi automatically joins the WiFi network after upgrading. This is necessary if the Pi is located in a remote or hard to reach location.

Especially on older Pis, the upgrade will take several hours, so plan accordingly.

If you have physical access to the Pi, consider making a backup of the SD card with the SD Card Copier utility (red berry menu in the top left >> Accessories >> SD Card Copier). If the SD Card Copier is not in the menu, you can install it with sudo apt install piclone.

한글과 유니코드

유니코드에서 한글을 어떻게 다루는지를 정리하였다.

유니코드

• 유니코드(Unicode)는 전 세계의 모든 문자를 컴퓨터에서 일관되게 표현하고 다룰 수 있도록 설계된 산업 표준 (위키 백과)
• 단순히 문자마다 번호를 붙임
• 계속 업데이트되며 현재는 Unicode Version 9.0.0 이 최신이다.

UTF

• 유니코드를 실제 파일 등에 어떻게 기록할 것인지를 표준화한 것이다.
