how to use ejabberdctrl set_vcard with non latin words in values? - ejabberd

Question

version that I use:
ejabberd 16.01 is running in that node
Filling values of set_vcard/set_vcard2 with non latin symbols (for example, in russian - НА РУССКОМ) cause errors.
this construction works fine:
ejabberdctl set_vcard user27 jabber.mydomain.local FN "27 operator"
ejabberdctl set_vcard user27 jabber.mydomain.local NICKNAME "27 operator"
but if I want fill it with Cyrillic words like this:
ejabberdctl set_vcard user27 jabber.mydomain.local FN "27 Оператор"
ejabberdctl set_vcard user27 jabber.mydomain.local NICKNAME "27 Оператор"
it not works, in current version of ejabberd, but in earlier versions this command line worked fine.

Please, tell how solve this problem?

Answer 1

It works for me using ejabberd 18.01 and 19.08. I cannot try older ejabberd versions because they do not compile with my current Erlang.
$ ejabberdctl get_vcard user27 jabber.mydomain.local FN
error_no_vcard_found
$ ejabberdctl set_vcard user27 jabber.mydomain.local FN "27 Оператор"
$ ejabberdctl get_vcard user27 jabber.mydomain.local FN
27 Оператор

Install a newer ejabberd version, which probably has that problem solved. I don't know which exact version solved it. You can install ejabberd in a test machine, check if that feature works correctly, and then focus in installing it in your online server.
