Before modifying the software, your terminal emulator must have access to a font that contains Japanese glyphs. For a matrix effect, a crisp monospaced font works best. Recommended Fonts
The core issue is that CMatrix doesn't control which font your terminal emulator uses to draw characters. Your terminal application (like GNOME Terminal, Konsole, or Alacritty) relies on your system's installed fonts to render text. When you run cmatrix -c , the program sends a stream of Japanese Unicode characters to the terminal. If your terminal's default font doesn't support these characters, it fails to draw them.
You have installed the font and run cmatrix -u 3 , but you still see � . Here is the fix:

Rendering complex Japanese Kanji in a fast-scrolling terminal window requires more processing power than simple ASCII letters.

Try changing your terminal's font to Droid Sans Mono or DejaVu Sans Mono if Noto is not working. Before modifying the software, your terminal emulator must
Standard versions of cmatrix include a flag specifically designed to trigger alternative character sets, including Japanese Katakana, provided your system environment supports it. The Standard Matrix Flag Execute the command with the lambda/alternative text flag: cmatrix -L Use code with caution.
In the original Matrix movie, the famous green code consists of inverted numbers, letters, and—crucially—. By default, some versions of CMatrix might only show alphanumeric characters. Configuring a Japanese font ensures you get the full, authentic aesthetic. 1. Installing CMatrix
Add some kanji for a denser look:
In newer updates of the package, developers added specific flags to emulate the true film look. Check your local man pages to see if your version supports native Japanese switching: man cmatrix Use code with caution. Your terminal application (like GNOME Terminal, Konsole, or
Once your terminal supports Japanese characters, you need to tell CMatrix to use them. Method 1: The -j Flag
For many, CMatrix is the quintessential piece of Linux "candy"—a terminal-based program that brings the iconic green "digital rain" from The Matrix films to life. It’s a staple for adding a touch of hacker-chic to any terminal session.
