Encoded URLs with some DEcoded - treated as same?

[JohnRoy]

If

example.com/widgets,+unique

shows same content as URLencoded page

example.com/widgets%2C+unique

1. Would that be considered same or duplicate page in Google?

2. If it's the same, does it matter how links TO this page(s) are showing?

I've never seen evidence that there's a canonical issue here - and I've certainly seen a lot of canonical problems. I'd suggest using the canonical meta tag as insurance.

I think they would be treated as duplicate as one page on my site used to have a space( ) in URL and WMT used to list them under duplicate title:
www.example.com/blue widget.html
www.example.com/blue%20widget.html

I replaced the space with hyphen and implemented the redirect, now things are fine.

Second question not answered yet:

2. If it's the same, does it matter how links TO this page(s) are showing?
