Tests for UTF-8 encoding in strings in source code. Patch by Seth Cantrell. llvm-svn: 143418

// RUN: %clang_cc1 -x c++ -std=c++0x -fsyntax-only -verify %s
// This file should be encoded using ISO-8859-1, the string literals should
// contain the ISO-8859-1 encoding for the code points U+00C0 U+00E9 U+00EE
// U+00F5 U+00FC

Improve the error message slightly for files that aren't using the expected UTF-8 encoding. Patch by Seth Cantrell. llvm-svn: 148991

Implement warning for non-wide string literals with an unexpected encoding. Downgrade error for non-wide character literals with an unexpected encoding to a warning for compatibility with gcc and older versions of clang. <rdar://problem/10837678>. llvm-svn: 150295

When checking the encoding of an 8-bit string literal, don't just check the first codepoint! Also, don't reject empty raw string literals for spurious "encoding" issues. Also, don't rely on undefined behavior in ConvertUTF.c. llvm-svn: 152344
