Both cursor positioning and text wrapping in FullScreenTUI used string.length (JS character count), but CJK/Hangul/fullwidth characters occupy 2 terminal columns, causing the blinking cursor to appear mid-text when input contained such characters. Added visualWidth(), visualLength(), visualWrap(), and visualCursorPosition() helpers accounting for double-width characters, and updated _renderInput(), render(), and _computeLayout() to use them.
