PHPMailer "basename"

[northmule]

When sending attached files in Cyrillic encoding, the file name is truncated. This is because in class "PHPMailer", functions "addAttachment" use "basename". Maybe you should use the WordPress feature in this place wp_basename.
For example, when sending a file through function wp_mail, we specify the file name / path / Файл.pdf - As a result, the file reaches the addressee ".pdf"

Hi there, welcome to WordPress Trac! Thanks for the ticket.

To clarify a bit, ​PHPMailer is an external library, so wp_basename() cannot be used there. Some other solution would need to be explored.

Yes, thank you for your answer. The solution of course in this case would be to call setlocale(LC_CTYPE, 'ru_RU.utf8') before wp_mail

This bug was already reported in #31775 and is related to #28407 which should make it possible to use a custom encoding function like wp_basename() for attachment names.
