Shell/terminal text rendering is garbled — characters replaced with black squares

[JaredT6694]

Bug Report

Component: CloudCLI Web Terminal

Description:
Text in the shell/terminal windows is largely unreadable. Characters are replaced with black filled squares (■), and many letters are missing or cut off, making it impossible to read command output.

Steps to Reproduce

1. Open the CloudCLI web UI
2. Open the terminal/shell panel
3. Run any command (e.g., task-master init)
4. Observe the output — text is heavily garbled with missing characters and black squares

Expected Behavior

Terminal text renders cleanly and is fully readable.

Actual Behavior

Most characters are replaced with ■ symbols or are missing entirely. Only fragments of words are visible (e.g., "e ect" instead of "Select", "o igu" instead of "configure"). The ASCII art banner in the box is also completely garbled.

Screenshot

Environment

• HolyClaude container (full variant)
• CloudCLI web terminal
• Xvfb virtual display :99

Likely Cause

Missing or incompatible monospace font in the container used by the web terminal renderer. The pattern of missing characters suggests a font substitution/fallback issue where glyphs are not available in the selected font.

Suggested Fix

Ensure a complete monospace font (e.g., fonts-dejavu, fonts-noto-mono, or ttf-anonymous-pro) is installed in the container and configured as the default terminal font in CloudCLI.
