The Active Code Page is the encoding used by the "A" functions of the Windows API (as opposed to the "W" functions which use UTF-16le).

The ACP was system-wide until very recently, and it's based on Windows's language. A US English Windows uses 1252.

An application can now choose to use UTF-8 (65001) instead.

Did you perhaps change your perl's code page to UTF-8 using this procedure?

could it be a bug?

No.
