Cannot translate "Next ›"

I cannot reproduce this bug. "Next ›" is included in the Italian translation as "Seguente ›". Below is a screenshot of the built-in Drupal content view. There must be other steps to reproduce.

@cilefen I'm afraid there's a character that makes a tricky possibly unnoticed difference: "›" and ">". Both "Next ›" and "Next >" are translatable and apparently the first one is involved in a pagination bar I see at the bottom of a view. I did translate "Next ›" but I keep on seeing it in English.
As for the pagination bar at the bottom of /admin/content view, curiously I see a "Last" and not its translation. The translation for the single word "Last" is set in /admin/config/regional/translate, though I cannot see the effect.

As this is a bug report, at this stage I think we need the steps to reproduce starting with a clean Drupal 10 installation. If you don't have access to a local platform you can use https://simplytest.me.

I just discovered something: the labels for the buttons of the paginator can be assigned upon choosing the paginator for the view, and probably the strings chosen there override any other translation; please see the attachment. Bye deciding there the value for the labels I could get the desired result. I cannot tell whether this is a predictable and if this is the desired behavior. I don't have a clean Drupal 10 installation handy. I went on simplytest.me, but there with the Olivero theme I could get just a pager without strings: why? Please see the attachment.

I couldn't attach more than one file, before. I attach now the clip with the form for the paginator and the settings for the labels.

Tried now with Claro theme. I couldn't get the Next and Previous buttons, but I got First and Last, and I could not see them translated. Then I changed the settings for the pager of the view, and eventually could see the Italian words I had chosen in the form for the pager.

I attach the clipping with the strings I could see translated after using the form for the settings of the pager.

No additional info provided so I'm closing this, if anyone is able to reproduce it please update the issue summary with steps.
