Hi there,

thanks for the code it’s exactly I was looking for.
Could you just help me out with one more thing? How can I read utf-8 files?

@shahab, sorry this is not a forum where you can ask questions like this. I suggest to bring this problem in a forum like http://www.codeguru.com/forum.

Sorin, if you’re using _wfopen() with css=UTF-8, you automatically add BOM chars to the file beginning. The BOM should create more disadvantages then advantages.
For instance, if you open again the same file created with the same parameters (just to change your file content) then you must be careful to remove the old BOM chars section, because otherwise you have two BOMs.
I met this situation in the past into a bug of one of my colleges and it isn’t to pretty.
I use std::ofstream class and a class conversion that contains a similarly conversion method, Marius’s sample.

I used this in order to create UTF-8 files:
_wfopen(strFile, L”wt, ccs=UTF-8″);

Nothing else needed.

Thanks for this article, Marius. It was exactly what I needed to know.

I sometimes wonder how I managed to do my job before the internet was around…
