Zig treats paths, arguments and environment values as byte slices; the port converted them lossily in many places. Now (final-Z1.md): - argv, env (incl. present non-UTF-8 values), HOME, PATH lookup, passwd, resources dir, TMPDIR, cgroup, config path canonicalization, +validate-config, +list-themes and Zig-string escapes (\xFF) keep raw bytes. String-based config values carry bytes via ghostty_os::osbytes, a bijective escape (noncharacter U+FDD0 + byte) that leaves all valid UTF-8 - including Nerd Font private-use icons - unchanged. - os/file rlimit fallbacks exist on all targets. - i18n locale canonicalization is an exact port of libintl's tables (e.g. pa-Guru -> pa_IN). - New ghostty-build-info crate is the single source of version, channel, commit and build mode for all consumers. Test Plan: - cargo test -p ghostty-os -p ghostty-config -p ghostty-cli (incl. randomized osbytes round-trip property tests)
