[Bug 1665618] Re: build tmux with utf8proc to allow utf8 in status line

[ChristianEhrhardt]

The Debian bug lead to a discussion around the right solution and terminal configs.
Eventually it led to conclude with:

Yes, glibc was updated to Unicode 9.0.0 a few days ago so version 2.26
will, indirectly, fix this:

https://sourceware.org/git/?p=glibc.git;a=commit;h=0b38d66a4e2e0d7cb9f40da5bc6e795e20cf3088

That said, adding a glibc task here

Title:
  build tmux with utf8proc to allow utf8 in status line

Status in glibc package in Ubuntu:
  New
Status in tmux package in Ubuntu:
  Triaged
Status in tmux package in Debian:
  Fix Released

Bug description:
  This version of tmux seems to be built without utf8proc, which leads
  to strange utf8 bugs in the status line. See e.g. the attached image
  on what happens if the program name has a multibyte char in it (by
  using `printf '\033k💻NAME\033\\' `).

  Could we have tmux built with --enable-utf8proc? It would give a
  runtime dep on libutf8proc2 and build-dep on libutf8proc-dev.
