panic info: Must use _os lookups with Arg::allow_invalid_utf8 when executing rust_hero data/.

[WenyingXiongwy]

env:
OS: x86_64 ubuntu 20.04.3 LTS
rustc: rustc 1.73.0

When I tried to test the ability of the executable binary tool rust_hero using data/error.rs based on the information in the readme, it failed to run and gave the following detailed error message:

/xxx/clap-3.2.25/src/parser/matches/arg_matches.rs:1843:13:
Must use `_os` lookups with `Arg::allow_invalid_utf8`
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace

Here is the call stack information printed by the gdb tool.
