If you are running an X11-based environment, you can force the terminal emulator to launch a specialized environment running the matrix with Japanese font overrides:
because it supports Katakana out of the box and handles modern terminal rendering better. Ask Ubuntu Method 1: The Modern Alternative (Recommended) cmatrix -c isn't working, use
), but this often results in a blank screen or missing characters if your system lacks the correct "wide" characters or ncurses support. Manjaro Linux Forum 🚀 Quick Setup Guide For the best experience, many users now recommend over the original
CMatrix operates on Unicode. It can output Katakana characters ( ア , イ , ウ , エ , オ ) natively using specific command flags. However, if your terminal is configured to use Monospace , Courier New , or Consolas , those fonts usually lack extensive Japanese glyph support. You will see ugly squares (�) or blank spaces.

Many users prefer Unimatrix , a Python-based alternative that handles half-width katakana (the "true" Matrix look) more reliably without complex compilation. Run with : unimatrix -n -s 96 (for Japanese characters). Troubleshooting Enabling Japanese in Cmatrix - Manjaro Linux Forum
Most users find that simply running -c results in a blank screen or broken ASCII symbols.
sudo apt install fbterm fbterm -f NotoMonoCJK cmatrix -u 3
This is such a common issue that it has been raised as a bug in the CMatrix project itself. The main complaint is that while the help pages tell you you need a Japanese font, they provide no guidance on what font to use or how to install it. The solution, therefore, lies not within CMatrix, but within your Linux system. If you are running an X11-based environment, you
Since cmatrix often uses printw (ncurses), you might need to adjust the print logic. If the internal buffer stores char , you should change it to store a pointer or an integer representing the Unicode code point, or simply treat the "character" as a string during rendering.
But there is a problem. The default cmatrix experience is distinctly Western. It uses ASCII characters ( 0 , 1 , % , $ , etc.). While nostalgic, it lacks the dense, vertical complexity of the original film’s "digital rain." In the movie, the iconic code wasn't random letters; it was a mix of Latin characters, reversed letters, and—most importantly—.
Your terminal is using an encoding other than UTF-8, or the selected font completely lacks CJK character mappings. Double-check your terminal settings and your $LANG environment variable.
If you run this and see blank spaces or question marks, your terminal font is the bottleneck. It can output Katakana characters ( ア ,
Look for the LANG variable. If it does not end in .UTF-8 , temporarily set it or add it to your ~/.bashrc or ~/.zshrc : export LANG=en_US.UTF-8 export LC_ALL=en_US.UTF-8 Use code with caution. Alternatives: Modern Terminal Matrix Simulators
Here is the complete guide to setting up Japanese fonts, installing the correct packages, and configuring your terminal for a customized cmatrix experience. Why Use Japanese Fonts with CMatrix?
Change your terminal font specifically to a Monospace or Gothic variant (e.g., IPAMonospace ). To make things even easier, let me know: Which Linux distribution or OS you are currently running.
