Node ID and node title in panels page URL I would like to set up Panels page URL with this pattern: my-site/[node:nid]/[node:title] (i.e. my-site/34/node-34-title).

I don't exactly understand how the Panels page URL setting works with arguments. I can set up the path to my-site/%nid/%title but how can I set it up so that %nid = [node:nid] and %title = [node:title]?

My questions:


How do I configure Panels page to do that?
Panels panes are populated with Views field. Is there anything to do in views to get these arguments?
How can I get transliterated node titles, using Pathauto or Transliterate?


Thanks!
Don't try to change the url with panel page manager: 

The path pattern is a way to target some page by there route. 

1 - If you want to modify the url pattern, use instead the  Pathauto pattern tool with Token. ex: /[node:title].

Once you build your pattern, it will create some alias every time you create a node, but the internal url is still /node/%node, so you have to use this one to target the nodes pages in the panel configuration. 

2- Then, if you need to use the node title in a  panel region, you can create a block view with title, and add a the contextual filter on the ID field, by taking is value frome the url.

3- If you build a pattern like in 1 - with pathauto and token - the resulting alias will be a transliteration of the node title.
