No, your program will still instruct the kernel to do the same. It will just cause conflicts with the other OS internals.

Adding another encoding as a gconv module. The DNS issues everyone is talking about.

I don't know what that gets you compared to using syscall(2) and -static. When you want your program to depend on the kernel API instead of the OS API, then you should really link libc statically.

But not with the kernel.

"Other OS internals" are just replaceable components. The idea is to depend on Linux only, not on Linux+glibc.

Those are glibc problems, not Linux problems. Linux does not perform name resolution or character encoding conversion.
