v1.70.0 - Non-UTF-8 locale fix via libtmux 0.58.0

on GitHub

tmuxp 1.70.0 bumps libtmux to 0.58.0, fixing session and window listing on systems whose locale is not UTF-8.

libtmux 0.58.0

libtmux's subprocess output decoding previously relied on the system locale. On non-UTF-8 locales, the format-separator byte sequence could be corrupted, causing tmuxp's session and window listing to silently return empty results.

libtmux 0.58.0 forces UTF-8 encoding in subprocess.Popen, eliminating the locale dependency. See the libtmux 0.58.0 release.

What's Changed

• py(deps): Test against libtmux utf-8-encoding branch by @tony in #1045
