Skip Unicode character expansion in assembly files Summary: When using the C preprocessor with assembly files, either with a capital `S` file extension, or with `-xassembler-with-cpp`, the Unicode escape sequence `\u` is ignored. The `\u` pattern can be used for expanding a macro argument that starts with `u`.
