Wstring unicode file

Didn't work for me. Community Bot 1 1 1 silver badge. David: Technically, a wstring is just an array of bit integers on Windows. Philipp the console is a whole world of pain! Even getting it to display non ANSI code points is an exercise of extreme masochism! Philipp Very interesting! I'm used to Python on Windows which has rubbish console support. Show 26 more comments.

Why don't you use data types like std::wofstream? Notice the w! The technique does work though. I wrote an encrypted stream that accepts wstrings and it properly stores and loads the data. However, this approach obviously would not work for a log file.

Thank you again for the suggestion. Is there anyway to keep it from converting it back to the multibyte code page? Is this atypical behavior for a compiler?

If the file is opened in binary mode, it will write a UCS sequence two-byte Unicode sequence to the file. It seems to be pretty successful so far. I currently was using either bytes or bytes. Thank you for your help and suggestions everyone. It is also marginally slower than the STLport implementation. Is there any reason for the drastic difference in speed? So, instead of just invoking utf8. However, this code might actually not compile. There are some ways to prevent that.

This will prevent the definition of the min and max Windows-specific preprocessor macros. Note how the function is invoked passing zero as the last argument. Allocating Memory for the Destination String If the Win32 function call succeeds, the required destination string length is stored in the utf16Length local variable, so the destination memory for the output UTF string can be allocated.

For UTF strings stored in instances of the std::wstring class, a simple call to the resize method would be just fine:. Still, checking the API return value is certainly a good, safe coding practice:. Basically, this Unicode encoding conversion module consists of two header files: utf8except.

The latter implements the actual Unicode encoding conversion functions. Note that utf8except. In contrast, utf8conv. To reuse this code in your projects, just include the aforementioned header files. The downloadable archive contains an additional source file implementing some test cases, as well. He also writes a blog at blogs.
