Hi, I am using version 3.14.0 and I am unable to view correctly characters like lines in a graph:
This is a view from a normal ssh terminal:
Output of locale:

LANG=C.UTF-8
LANGUAGE=
LC_CTYPE="C.UTF-8"
LC_NUMERIC="C.UTF-8"
LC_TIME="C.UTF-8"
LC_COLLATE="C.UTF-8"
LC_MONETARY="C.UTF-8"
LC_MESSAGES="C.UTF-8"
LC_PAPER="C.UTF-8"
LC_NAME="C.UTF-8"
LC_ADDRESS="C.UTF-8"
LC_TELEPHONE="C.UTF-8"
LC_MEASUREMENT="C.UTF-8"
LC_IDENTIFICATION="C.UTF-8"
LC_ALL=

and $LANG is C.UTF-8

Also when using tmux, the bottom status bar has problems rendering, for example it "piles up" showing multiple times like here:

I did more testing, and seems to be related to the way GSON handles data in java side.

For example, testing input by sending ạ is correctly encoded in javascript by JSON.stringify, then is send as binary data via connection.send.
However the terminal output displays a "?"

And writing in the terminal: printf "\u1EA1\n" and executing, deliveres to javascript an e.data already broken (notice the ��� instead of ạ ):

[{"sessionId":75,"output":"\r\n\u001b[?2004l\r���\r\n\u001b[?2004h\u001b]0;ubuntu@gpu01: ~\u0007\u001b[01;32mubuntu@gpu01\u001b[00m:\u001b[01;34m~\u001b[00m$ ","id":1,"displayNm":"gpu01.ashburn","user":"ubuntu","host":"gpu01.ashburn.poc.oraclevp.com","port":22,"authorizedKeys":"~/.ssh/authorized_keys","checked":false,"statusCd":"INITIAL","instanceId":1}]

Maybe could be related for output to using sendText instead of sendBinary here: https://github.com/bastillion-io/Bastillion/blob/d1e88b8578ab81edd7184ea7864bbf7647139422/src/main/java/io/bastillion/manage/task/SentOutputTask.java#L49

And for input, here: https://github.com/bastillion-io/Bastillion/blob/d1e88b8578ab81edd7184ea7864bbf7647139422/src/main/java/io/bastillion/manage/socket/SecureShellWS.java#L70
It is accepting onMessage String which is UTF-16, instead of binary to be decoded as UTF-8 with StandardCharsets.UTF_8 before parsing with GSON
