Hello!
Some data source has commas in directory names. Because of that data transfers fail with an error as below:
illegal characters - use only A-Z a-z 0-9 / SPACE .-_~#:^ /some-long-path-here/PDE_0,1pe/dirname/filename.dat; Invalid or incomplete multibyte or wide character
I wonder if it’s EOS limitation by design or it’s a bug?

Hi Nikolay,
The eos instance needs to be configured to accept any UTF8 characters and for this you need to set the following env variable in the /etc/sysconfig/eos_env
file:
EOS_UTF8=0
Cheers,
Elvin
Dear Elvin,
Thanks a lot for your reply!
Dear Elvin,
I tried copying file with comma in filename without “EOS_UTF8=0”. With command:
gfal-copy /etc/hostname root://junoeos01.ihep.ac.cn//eos/juno/dirac/juno/user/z/zhangxt/a,a
It took much time so I use Ctrl+C
to stop the command. It caused a mgm crash and here is the mgm logs:

My eos instance version is 4.8.62 and gfal-copy version is 2.18.0.

Hi Xuantong,
I think the crash at the MGM is not related to the gfal-copy command. It seems the crash comes from a “rm” operation. You should get a detailed stacktrace after the messages that you pasted. If you can paste that one, we can more easily understand the root cause.
Thanks,
Elvin

Hi Xuantong,
I think this commit fixes the crash that you saw:
https://gitlab.cern.ch/dss/eos/-/commit/a7f3845c25ba5579e69b8ab13b4a65feaf486885
This was released in eos-4.8.63.

Dear Elvin,
Thanks for your reply. I will try it when my eos instance upgrades to 4.8.63.
