I understand mosh does something with respect to ANSI escape sequences, but I don't quite understand it. Using ssh, running the 'tree' command looks like this:

$ tree
.
├── [   0]  one
├── [   0]  three
└── [   0]  two

0 directories, 3 files

But, through mosh, it looks like this:

$ tree
.
tqq [   0]  one
tqq [   0]  three
mqq [   0]  two

0 directories, 3 files

Is there something I can do to make this display properly?

Can you check to see if you have NCURSES_NO_UTF8_ACS=1 in your environment?

FingerCramp commented 2 years ago

I do not.

I have no NCURSES env vars set at all.

Can you try to set NCURSES_NO_UTF8_ACS=1? mosh-server sets this automatically, but sometimes it can be dropped (if you ssh into another system, or if you attach to a screen/tmux session that doesn't have it set)

FingerCramp commented 2 years ago

Unfortunately, it didn't help. :(

I cannot reproduce this with a mosh-client 1.4.0 connected to a mosh-server 1.3.2 on Ubuntu 18.04.

This is what I see

What is $TERM outside of mosh? What terminal is being used? Can you post the rest of env and locale?

FingerCramp commented 1 year ago

Thank you for the reply.

Before moshing to the remote system, my $TERM is the same:

Mike/Macbook- echo $TERM xterm-256color

I'm using the iTerm2 terminal (Build 3.4.19). Before connecting to the remove host, my env and locale are:

That's very weird. I still can't reproduce the behavior you're seeing, but I'm admittedly using Terminal.app, not iTerm2. Any chance you could post the output of infocmp to see what ncurses thinks is going on? Maybe there's some weird local override? Because it seems like, despite NCURSES_NO_UTF8_ACS=1 being set, tree is emitting the Line Graphics characters and not the UTF-8 alternatives.

For example, in Terminal.app directly

 $ tput smacs && echo tqq && tput rmacs
├──

but in mosh --local 127.0.0.1 inside Terminal.app

$ tput smacs && echo tqq && tput rmacs

I'm not sure if you're looking for the infocmp output on local or remote host, so I'm providing both, below. Please let me know if I can provide anything else to assist here.
