Question

I read a file that has utf8 characters like this:

FILE *FileIN,*FileOUT; FileIN=fopen('filename','r'); char string[600]; WideChar C[600],S[100]; fgets(string,600,FileIN); wcscpy(C,UTF8Decode(string).c_bstr()); // widechar copy 

And it reads it perfectly (this is shown in the Editbox when running the program):

Edit1->Text=C;  Result ===> '3021';'亜';'7';'ア アシア つ.ぐ T1 や つぎ つぐ' 

The thing is that when I want to write this on a file:

FileOUT=fopen('txt.txt','w');     fwrite(Edit8->Text.c_str(),strlen(Edit8->Text.c_str()),1,FileOUT);  Result ===> '3021';'?';'7';'? ??? ?.? T1 ? ?? ??' 

The question is, how do I write the result (the one i can see in the program running) in a file?

I use C language on CodeGear C++Builder

Resolved thanks to Christoph and nobugz for the help

I changed this line

fwrite(Edit8->Text.c_str(),strlen(Edit8->Text.c_str()),1,FileOUT); 

to this one and it worked. Thanks

fwrite(UTF8Encode(Edit8->Text).c_str(),UTF8Encode(Edit8->Text).Length(),1,FileOUT);

I don’t know the framework, but if you use UTF8Decode() after reading the file, shouldn’t you use UTF8Encode() before writing?
