So it is garbled only in the compose form? Could you provide the filename here as a text, so I can create such a file in my system and test this?

attachment filename is "あいう.txt"

compose form - "あいう.txt"
INBOX(from roundcube) - "あいう.txt"
INBOX(from other mail system) - "あいう.txt"

I cannot judge whether my system configuration is wrong or not.

But your screenshot shows correct filename in mail preview. So, I'm confused. Anyway, I can't reproduce. This may be browser-specific or server-specific or client-OS-specific. So, try with another browser, try with disabled plugins. If this does not help, you'd need to debug in the code.

I wanted to show that a received mail through other system is correct. I'm sorry for confusing you.

• roundcube(garbled) -> send -> roundcube(garbled)
• roundcube(garbled) -> send -> gmail(garbled)
• gmail(correct) -> send -> roundcube(correct)
• gmail(correct) -> send -> roundcube(correct) -> forward -> roundcube(correct)

I already tried Chrome, IE and Edge. Results are no change.
and already encoded mail by other system (=forwarding mail) shows correct filename. so I think this is my server side issue.
Thank you for the information.

I solved this issue. Thanks.

mbstring is a requirement in 1.2, so did you just install it or it was some configuration "broken"?

Code Select Expand

Beginning with PHP 4.3.3, if enctype for HTML form is set to multipart/form-data and mbstring.encoding_translation is set to On in php.ini the POST'ed variables and [b]the names of uploaded files will be converted to the internal character encoding[/b] as well.
PHP got me. I changed mbstring.http_input = "auto" to "pass". It works fine.
