-+/* On the Mac, we define U_WCHAR_IS_UTF32 to treat wchar_t as though it
-+   contains UTF-32 at all times.  Strictly speaking, that's not entirely
-+   correct given Mac's libc (__STDC_ISO_10646__ is not defined) , but provided
-+   that we ignore libc's locale support (by not calling setlocale) and its
-+   multibyte string support, this should be fine.  Our codebase makes enough
-+   other assumptions about a UTF-8 locale and UTF-32 wchar_t strings for this
-+   to make sense. */
