PrettyURLs: Empty title when no latin character is present

[azett]

Reported by blog7 on the support forum: If an entry's title consists of only non-latin characters (such as "Титул" for "Title"), they will be completely stripped, leading to a permalink without title like example.org/index.php/2020/06/01//. This then leads to the overpage of all entries of that day, not to the single entry itself.

Title sanitation takes place in sanitize_title_with_dashes() (core.wp-formatting.php).

Idea: A plugin that allows for storing a Latin-only alternative title for each entry?

Needs to be inspected!
