Use ! to enter the shell, how to output Chinese without garbling

For reference: the garbled CJK output when entering shell mode (!) on Windows is fixed by #1418 (merged in aae0243). The interactive TUI shell-mode path now forces UTF-8 output for PowerShell/cmd subprocesses, so Chinese output renders correctly. This will ship in the next release.

中文：补充说明 — Windows 下用 ! 进入 shell 模式输出中文乱码的问题已由 #1418 修复（合并于 aae0243）。TUI shell 模式现已为 PowerShell/cmd 子进程强制开启 UTF-8 输出，中文可正常显示，将随下个版本发布。
