##### SUMMARY
Mentioned modules should allow to select encoding for a file (defaulting to utf8 or utf16)
I have a requirement to generate simple files with ascii encoding. I can't do that with neither win_copy nor win_template

win_copy currently creates file with UTF16
##### ISSUE TYPE
- Feature Idea

##### COMPONENT NAME
win_copy
win_template

##### ADDITIONAL INFORMATION
Tested on WinSrv 2016, PS-5.1
```yaml
- name: Bootstraping
  hosts: all
  tasks:
    - name: Deploy file
      win_copy:
        content: 'text'
        dest: 'C:\some\path.txt'
```

- When set to C(yes), create a backup file including the timestamp information
      so you can get the original file back if you somehow clobbered it incorrectly.
