clang unicode characters for variable name

cat test.cpp

#include <iostream>

int main() {
  int à;
}

results in:

clang++ test.c开发者_如何学编程pp
test.cpp:4:7: error: expected unqualified-id
  int à;
      ^
1 error generated.

Now, is there a way to get clang to allow unicode variable names?

Thanks!

While this is allowed by the standard, Clang does not currently support UCN (universal character name)s in identifiers.
