Hi. I have had problems compiling a simple program that uses wstring. So....I wrote a small application that reads using char, fgetc etc in a text file and writes it out to another text file. The japanese was preserved in the outfile. I am a c++ programmer from Microsoft and I use TCHAR etc so I am no stranger to unicode on windows. I am using eclipse, cgywin, windows 2k (Japanese Language support). gcc 3.3.3. So why would I use wstring and wchar_t when string and char work with Japanese anyway? Thanks.

Why would you use something you don't seem to need? V Back to top DFB_NZ Guest Posted: Fri Jan 28, 2005 7:02 pm    Post subject: Re: stl wstring and string. Could you be more specific about "This is covered in the FAQ 5.8." ie could you please paste a URL link or something. I found that even in MSVC 6.0 if I use char and read/write a japanese file the japanese is preserved. I am confused. I thought I had to use TCHAR everywhere for non-ascii text. I compiled using MBCS and therefore used char to read in japanese text then write it out to a text file. the output file still had japanese in it. Can someone offer anytype of explanation..?

If you open files in binary mode and use the "C" locale you can use narrow streams for transfering data without regard to its textual content. If you need to do more than transfer data between files, e.g., if you need to perform regex subsitutions, you should imbue the file stream with an appropriate local and use wide characters.

Reading and writing narrow characters will work fine as long as your program basically just passes the text through without caring about how many of those narrow characters go to compose on real Japanese character. If, however, your program needs to deal with the characters as characters and (for example) cares about the boundary between one character and the next, then converting them to wide characters will start to make a lot more sense. The Unicode encodings are mostly pretty easy (UCS-4 is trivial, but even UTF-8 is still fairly simple) but (just for one example) Shift-JIS is seriously ugly, to put it nicely -- if you have to deal with it, you'd strongly prefer to use some pre-written code. Of course, UCS-4 is rare and Shift-JIS almost unavoidable... -- Later, Jerry. The univserse is a figment of its own imagination.

This was posted earlier in this very thread: http://www.slack.net/~shiva/welcome.txt Go there. It leads to the FAQ. If you are too lazy to do that, I am not inclined to help and many other will feel the same way.
