how to read txt file which has char or unicode ?

mc 4,576

I can not use std::fstream right?

If I set locale I can not read normal char If I do not set it I can not read unicode bytes.

The character encoding doesn't matter if you read the file as a binary file. Windows has the IsTextUnicode function to help you determine the encoding of the data you read from a file. Additonally, you can check the buffer into which you read the data to see if it contains a BOM.

Maybe I wasn't clear about what I meant. You can test some data from the file to determine if it is or is not unicode.

For example,

if(FileIsUnicode()) { // code for a unicode text file } else { // code for other than unicode }

You would write the FileIsUnicode function that can call the Windows API IsTextUnicode function as well as check the test data for the presence of BOMs.
