Encode batchfile in current codepage. (#913)

Changing chcp breaks cmd.exe if switching from multi-byte to 65001.
cmd.exe depends on codepage to parse batchfile
so batchfile cannot have unicode characters.
Target powershell if unicode support is required.

User should fix their terminal font to display unicode characters.
Terminal programs can only use Wide String APIs.
For Vim, this requires +multi_byte feature and `set encoding=utf-8`
in the user's vimrc.
Neovim always defaults to `set encoding=utf-8`.
