The format in which data is written to a file is unrelated to any kind of API. It's all just bytes as far as the operating system is concerned.

If you have a text file, you can change the code page of the written data using the http://www.freepascal.org/docs-html/rtl/system/settextcodepage.html function. Passing CP_UTF8 will result in all data written to it to be converted to UTF-8.

thanks Jonas , this function (SetTextCodePage) is what was missing  , now the resulting file contain correct text

this is for text file , what if i want to write utf-8 text to a binary file ?

A binary file is just arbitrary bytes. If the bytes you write represent UTF-8 text, then your file will contain UTF-8-encoded text.
