UTF-8 mode
Tests whether the terminal correctly handles UTF-8 encoded text. Virtually all modern terminals default to UTF-8 mode. UTF-8 encodes Unicode code points as 1-4 byte sequences, allowing the full range of Unicode characters (emoji, CJK, mathematical symbols, etc.) to be displayed in the terminal.
