file name appearing as question marks when downloading all attachments

[Zeyu Wang]

Non-ASCII characters appearing as question marks only when downloading all attachments.

those characters appear correctly in the page and when downloading separately.

Following the troubleshooting article,  i tried to run  the encoding test and checked database collation and character set.

here is the result.

encoding test

----

>> File was written successfully

Detect whether the file system is mangling the file name when it is saved
>> the file name has been mangled

---

database collation and character set

all are  utf8mb4_bin

After adding the following to my setenv.sh file, all encoding tests pass:

export LC_ALL=en_US.UTF-8
export LANG=en_US.UTF-8
export LANGUAGE=en_US.UTF-8
