Sometimes it is useful for a program to be able to run a child process and
more or less depend on its output being valid UTF-8. This can usually be
accomplished by setting one or more environment variables, but there is
the question of what to set them to - what UTF-8-capable locale is present
on this particular system? This is where the utf8_locale library
comes in.
For the Rust implementation:
use std::process;
use utf8_locale;
let utf8env = utf8_locale::Utf8Detect()::new().detect()?;
let cmd = process::Command::new(...).env_clear().envs(utf8_env.env);
For the Python implementation:
import subprocess
import utf8_locale
utf8env = utf8_locale.Utf8Detect().detect()
subprocess.check_output([...], encoding="UTF-8", env=utf8env.env)
The source of the utf8-locale library may be obtained at
its devel.ringlet.net homepage. It is developed in
a GitLab Git repository.
The current version of utf8-locale is utf8-locale-1.0.0:
