Align the URL creation of HST pages with document and xpage URL creation

Channel manager creates urls with special characters (utf-8) unlike normal links created in content tree
see:
https://xmdocumentation.bloomreach.com/library/concepts/content-repository/node-name-encoding.html

Reproduction Path: 
1 - Open a Channel in Experience manager

2- From Page menu, create a new page (HST/landing page)

3- Use a page name including accent such as "página"

4- Check the last element part for page URL

Expected: all characters in last element is converted to universal characters

Actual: characters with accent is not converted 

Requirements

During HST Page, XPage or document creation, when user inputs the name of the page or document, the URL or Last element of URL is created automatically based on input.

The expected behavior is: 
In the front-end, the automatic URL/last element creation should directly convert all characters to universal characters in HST Page creation. In the back end, the same conversion should take place so site map items are only saved in universal characters, sp without special characters.

If user manually edits the URL or last element, then the URL should be kept as it is provided by user considering this is an intentional change and responsibility is on user. then the conversion of universal characters should still be applied to be consistent with how the content URL names are handled. The edit function is only meant to have a different name, but still without diacritics and such.
