AskUserQuestion CJK text misalignment in terminal UI

When using AskUserQuestion with Traditional Chinese (CJK) text mixed with ASCII/numbers, the rendered options are misaligned — text appears to "drift" out of the checkbox/border layout. Likely a wide-character width calculation issue (CJK chars are double-width but may be counted as single-width). Screenshots attached showing the broken layout.
