1 month ago I can't reproduce this here. Unclear what's happening. I tried
use gio::prelude::*;
fn main() {
let path = std::path::PathBuf::from("立秋 feat.ちょこ - プナイプナイせんそう.mp3");
let file = gio::File::for_path(&path);
let _ = std::fs::File::create(&path).unwrap();
assert!(path.exists());
let basename = file.basename().unwrap();
let key = glib::FilenameCollationKey::from(basename.to_string_lossy());
println!("{} {} {:?}", file.parse_name(), basename.display(), key);
}and

}Also importing directories in Amberol git main with lots of files with Japanese filenames works fine here.
The error looks like GLib is returning us something that is not valid UTF-8.

1 month ago Testing with Python:
>>> import locale
>>> locale.strxfrm("立秋 feat.ちょこ - プナイプナイせん.mp3")
'立秋 feat.ちょこ - プナイプナイせん.mp3'
>>> locale.setlocale(locale.LC_ALL, "en_GB.UTF-8")
'en_GB.UTF-8'
>>> locale.strxfrm("立秋 feat.ちょこ - プナイプナイせん.mp3")

Ideally, the API documentation should make it clear that the input has to be UTF-8, but not the output.

Turns out that #1329 breaks code that does:
which now generates a debugging assertion:
and a backtrace like this one taken from Amberol:
