Subject Re: Karaf SSH invalid encoding
Date Mon, 12 Nov 2018 09:49:16 GMT
Hi JB,

I get this ( from Linux shell ):

[mm@mm1 ~]$ echo $LC_ALL

[mm@mm1 ~]$ echo $LANG
en_US.UTF-8
[mm@mm1 ~]$ echo $TERM
xterm-256color
[mm@mm1 ~]$

>From inside Karaf's Shell:

karaf@root()> shell:echo $LANG
en_US.UTF-8
karaf@root()> shell:echo $LC_ALL
null
karaf@root()> shell:echo $TERM
xterm-256color
karaf@root()>

This is when ??? is not present - it is working. I will post back when I
get/see ??? .

Kind Regards,
Miroslav
