is-unicode-supported reliably detects if the current terminal or environment fully supports Unicode characters. This tiny utility is essential for command-line interface (CLI) applications needing to display diverse characters or symbols correctly. It simplifies development by handling the complexities of platform and font configurations, ensuring consistent user experiences regardless of the underlying system. Use it to gracefully degrade output or implement alternative representations when full Unicode support is unavailable.
