The Rust programming language supports Unicode similarly to other modern languages. To handle Unicode characters efficiently and in a user-friendly way, Rust uses various techniques in parser and mangler.

I worked on Unicode support for GCC Rust last summer during Google Summer of Code 2023. At present, GCC Rust adequately handles Unicode characters, although there are still a few tasks left to be completed. In this talk, I will share my knowledge about Unicode and how modern compilers handle it.
