clang unicode characters for variable name

Question

cat test.cpp

#include <iostream>

int main() {
  int à;
}

results in:

clang++ test.cpp
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!

Is it standard C to have Unicode characters inside identifiers? — zneak, Apr 21 '10 at 22:30
`clang++` 3.4 supports this. Since 3.3 (http://llvm.org/releases/3.3/tools/clang/docs/ReleaseNotes.html#major-new-features) — alfC, Oct 30 '14 at 17:46

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

Are there any other restrictions on the use of Unicode by Clang? e.g., not in comments/strings, ...? – Ira Baxter Jun 13 '11 at 03:49
Clang supports UCNs in comments and strings. Although I'm not sure what the source charset has to be, or what it's converted to. – Michael Spencer Jun 13 '11 at 06:10
