Bug ID: 123702
Summary: `gcc_jit_context_new_function` doesn't accept Unicode
characters in function name
Product: gcc
Version: 15.2.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: jit
Assignee: dmalcolm at gcc dot gnu.org

Compiler output
C23 added support for Unicode characters in identifiers, but libgccjit didn't
follow suit. Really, there shouldn't even be a check for validity in the first
place, since LLVM, JVM, and I'm sure others don't have one, thus restricting
interoperability if we were to have one.
What I mean by this is that `gcc_jit_context_new_function`'s fifth argument,
`const char *name`, will not accept a UTF-8 string or any other Unicode format.
`gcc -v` (modified to split long lines):
