[Boost-users] [Boost.Locale] [Boost.Iostreams] Example with code converter does not work with clang

27 Mar 2012

      I'm trying the example on the "Character Set Conversions" page of the
Boost.Locale documentation:

http://www.boost.org/doc/libs/1_49_0/libs/locale/doc/html/charset_handling.h...

(the full code I'm running is at the end of this message).

When compiling with gcc:

g++ -o test -lboost_locale test.cpp

It run correctly - it prints "שלום" to standard output.

However, when compiling with clang:

clang++ -o test -lboost_locale test.cpp

0xc3 0x97 0xc2 0xa9 0xc3 0x97 0xc2 0x9c 0xc3 0x97 0xc2 0x95 0xc3 0x97 0xc2 0x9d

--------

What I'd like is to have a stream that accepts wide strings in the
current locale and produces narrow strings in UTF-8 - am I completely
off the track? If so, what should I do instead, and if not, what am I
doing wrong?

Thanks!

#include

#include 
#include <iostream>

namespace io = boost::iostreams;

class consumer {
public:
    typedef char char_type;
    typedef io::sink_tag category;
    std::streamsize write(const char* s, std::streamsize n)
    {
        std::cout.write(s,n);
        return n;
    }
};

int main()
{
    typedef io::code_converter<consumer> converter_device;
    typedef io::stream converter_stream;

    consumer cons;
    converter_device dev;
    boost::locale::generator gen;
    dev.imbue(gen("en_US.UTF-8"));
    dev.open(cons);
    converter_stream stream;
    stream.open(dev);
    stream << L"שלום";
    return 0;
}
