fix: change VBS encoding to UTF-16 LE to fix compatibility issues

[yolol1]

The original VBS script was encoded in GB2312 (ANSI), which causes execution errors and moji-bake on non-Chinese Windows systems (e.g., English Win11).

Converting to UTF-16 LE ensures the script runs correctly on all Windows locales by allowing the WScript engine to properly recognize characters.
