Well, what you're saying isn't entirely true, although the C++ Standard
library is indeed somewhat archaic in some aspects.
Let me set all this straight:
1. C++ nor any standard algorithm/function/class/... (except of course the
locale related things) has no idea about character encoding whatsoever.
This means that any C++ iostream or string (be it with char or wchar_t) can
handle unicode just fine; it just doesn't do anything for you. Which might
be the same as saying it doesn't handle it at all. Well, the standard
classes are certainly not useless for unicode (nor do they prevent you from
using them for this purpose). Just not very useful...
2. This missing function (open an ifstream with a "Windows native" wchar_t
pathname) is stupid for two reasons: a) Windows is stupid in not
implementing a UTF-8 interface to its C and C++ standard library. All other
(modern) OSes work just fine with the 8-bit char and UTF-8. And b) C++ is
stupid in not making things easier. Work is being done in the form of the
Filesystem library that has been implemented in Boost (mostly like the
proposal) and the most recent Visual Studio 2015 (VS2013 has Filesystem v2,
which is slightly different).
3. There is no such thing as the Win64 API. It's still the Win32 API. And
yes, these C-style functions can handle all of this just fine, if you use
the proper encodings yourself. (small footnote: a valid Win32 filename is
not per se a valid UTF-16 string, but the reverse is true. And as far as I
know, the Unicode normalization isn't specified, so it's a can of worms any
way you want to put it)
4. Boost indeed has the aforementioned Filesystem library, which gives you
an interface to interact with files and filenames in a portable way.
5. There are only 3rd party (not even Boost) Unicode solutions. Make sure
you really need this before going into this. Full Unicode correctness is
expensive and hard.
6. wchar_t does not solve the unicode problem. It has the exact same
drawbacks UTF-8 has. UTF-32 has most of those drawbacks as well. Unicode is
hard.
Yes C++ sucks. You haven't even seen half of it. It is also quite good at
doing things you didn't know it could do.
Enjoy learning it, think about platform compatibility before you start
writing code.
Compile with several compilers.
st don't mind MSVC too much, it tends to not get C++ well, although the
newest versions are significant improvements with each step.
Cheers,
Ruben
