Hi, I tried sending an attachment containing Unicode characters, and the attachment was sent successfully. But the Unicode characters were removed from the file name. For example, if I send an attachment named "你好.jpg", then the receiver will receive the file but it's named ".jpg" (unicode characters are removed). I want to keep the original attachment name, is there any solution? Thank you very much!
Code:
$this->email->attach("path/to/你好.jpg"); //attachment name contains Unicode characters
