Comment (by SergeyBiryukov):

 The issue with `pathinfo()` is that it depends on PHP locale and does not
 always work correctly with UTF-8 characters, leading to issues with
 truncated titles, see comment:40:ticket:37989.

 We've encountered similar issues with `basename()` before, see #21217 and
 #23267.

 [38294] needs a thorough test with multibyte file names. Some of the
 `pathinfo()` instances may need to be replaced with `wp_basename()`, which
 is the i18n-friendly version of `basename()`.
