I have found that ClawsMail cannot set the long filename to attachment correctly. _2旅費交通費精算書_201704_○○.xls ⇒ 旅費交通費精算書_201704_○○.x _2旅費交通費精算書_20170_○○.xls ⇒ 旅費交通費精算書_20170_○○.xl Is it some sort of limitation?
Probably just a bug in conversion from UTF-16 to UTF-8. When do you see this? When trying to attach a file to a new message?
Thanks for your reply. I attached the file just after create a new message. The attachment tab of that message is showing filename correctly. I can find the incorrect filename at sent-folder (and inbox -- I sent it me by BCC) after I send it.
I think this has been fixed in git already, in commit http://git.claws-mail.org/?p=claws.git;a=commitdiff;h=70ea2d8 Feel free to reopen if this is still an issue in an upcoming next release.
