Rust 1.53 Unicode Ident support

Const BLAHAJ: &str = "🦈"; Struct man {name: String,} let alpha = 1;Copy the code

Rust 1.53 supports Unicode characters as identifiers, which means that you can use them as long as they are legal Unicode. Corresponding to RFC 2457, this RFC also records which Unicode is not secure, you can check.

Teams can configure the Lint attribute, #[deny(uncommon_codepoints)], to disallow some unrecommended Codepoints.

That’s a bit much! Maybe the team needs to do some coding for Unicode identifiers.

A new MCP: merge rustc_codegen_gcc as a compiler/rustc_codegen_gcc component into Rust-lang /rust

Github.com/rust-lang/c…

Rustc_codegen_gcc is a GCC code generator for RUSTC, which means it can be loaded by an existing RUSTC front end, but benefits from GCC because it supports more architectures and can be optimized for GCC.
