Give a nicer error for non-Unicode arguments to rustc and rustdoc #42092
Conversation
This file contains hidden or bidirectional Unicode text that may be interpreted or compiled differently than what appears below. To review, open the file in an editor that reveals hidden Unicode characters.

Previously, any non-Unicode argument would panic rustc: ``` $ rustc $'foo\x80bar' error: internal compiler error: unexpected panic note: the compiler unexpectedly panicked. this is a bug. note: we would appreciate a bug report: https://github.com/rust-lang/rust/blob/master/CONTRIBUTING.md#bug-reports thread 'rustc' panicked at 'called `Result::unwrap()` on an `Err` value: "foo�bar"', /checkout/src/libcore/result.rs:859 note: Run with `RUST_BACKTRACE=1` for a backtrace. ``` Now it gives a clean error: ``` $ rustc $'foo\x80bar' error: Argument 1 is not valid Unicode: "foo�bar" ``` Maybe fixes rust-lang#15890, although we still can't *compile* arbitrary file names.
