Problem that Korean comments are broken when exporting stub code before CT 3.4 and importing after 3.4

In Stub view, when exporting stub code before CT 3.4 and importing stub code before CT 3.4 after CT 3.4, Korean comments are broken.

This is because the encoding of the stub code is ANSI until CT 3.3 and UTF-8 after CT 3.4. If you import stub code that was exported before CT 3.4, you must use an external editor to change the encoding to UTF-8 before importing.
