While writing a C program that delt with encryption, I needed to view some encrypted files determine their contents. I used cat to do so, and occasionally got some weird results.
- The Problem:
Printing one file would change the character encoding of the terminal, while another would change it back to the original.
-
I determined that there was a single character responsible in the file the binary file for changing the character encoding by reducing the file until
cat file.txtonly printed out single character in question. -
To confirm my tests, I wrote a simple C program that would print every ASCII character to a file, and deleted characters from the file until the my suspicions were confirmed.
The character in question is ASCII code 0x0E (^N), which turns the character encoding into an emoji style characterset, but only in tmux. The ASCII character 0x0F (^O) will turn the characterset back to the default character set.
If the encoding changes in tmux, I will print the character 0x0F (^O).
Determine whether this is a feature of tmux or a bug. If it is a bug, submit a bug report or a pull request at the Tmux source repository on Github
