byobu on restoring session does not display utf-8 symbols

[Srinivas]

When i open a new session the symbols like the logo are displayed correctly.

If I detach the session and then open again they are not displayed at all.

This also affects vim-airline in neovim.

If I detach a session in tmux and restore with tmux -u option this error does not occur. (Hope this helps)

I use byobu 5.116 and tmux 2.3 in ubuntu 17.04

def attach_session(session):
 update_environment(session)
 backend, session_name = session.split("____", 2)
 cull_zombies(session_name)
 # must use the binary, not the wrapper!
 if backend == "tmux":
  os.execvp("tmux", ["tmux","-u", "-2", "new-session", "-t", session_name, "-s", "_%s-%i" % (session_name, os.getpid())])
 else:
  os.execvp("screen", ["screen", "-AOxRR", session_name])

Adding -u parameter in os.execvp in /usr/lib/byobu/include/select-session.py Fixes the issue.

As I don't know how to use bazaar I am putting the fix here. Please fix it.

Hmm, that's not going to be the correct fix for everyone... You would be better served by setting your LC_ALL, LC_CTYPE and LANG environment variables correctly.

See man tmux:

     -u When starting, tmux looks for the LC_ALL, LC_CTYPE and LANG environment variables: if the first found con‐
                   tains ‘UTF-8’, then the terminal is assumed to support UTF-8. This is not always correct: the -u flag
                   explicitly informs tmux that UTF-8 is supported.
