32 * Starting with ICU 49, platform.h is a normal source file,
33 * to simplify cross-compiling and working with non-autoconf/make build systems.
42 * before it is first tested, or add an equivalent -D macro definition
46 * For example, with gcc you can compile an empty .c file and have the compiler
49 * gcc -E -dM -x c /dev/null | sort
52 * <code>-x c++</code> is for C++.)
72 * We used to define one different, value-less macro per platform.
76 * Starting with ICU 49, we define platforms as numeric macros,
92 /** MinGW. Windows, calls to Win32 API, but using GNU gcc and binutils. @internal */
96 * using MSVC or GNU gcc and binutils.

112 * Darwin is a POSIX-compliant operating system, composed of code developed by Apple,

140 * WebAssembly. It provides some POSIX-compatible wrappers and stubs and
141 * some Linux-like functionality, but is not fully compatible with

553 * <p>In other words, all the graphic characters in 7-bit ASCII should
586 * Hardcode the default charset to UTF-8.
589 * - ICU will assume that all non-invariant char*, StringPiece, std::string etc.
590 * contain UTF-8 text, regardless of what the system API uses
591 * - some ICU code will use fast functions like u_strFromUTF8()
592 * rather than the more general and more heavy-weight conversion API (ucnv.h)
593 * - ucnv_getDefaultName() always returns "UTF-8"
594 * - ucnv_setDefaultName() is disabled and will not change the default charset
595 * - static builds of ICU are smaller
596 * - more functionality is available with the UCONFIG_NO_CONVERSION build-time
598 * - the UCONFIG_NO_CONVERSION build option in uconfig.h is more usable
630 * The size of wchar_t was 1 but L"xyz" string literals had 32-bit units anyway.

657 * 16-bit in the 32-bit environment."
