\u00c8<\/code> is not an ASCII<\/a> character. Let’s assume the file is actually encoded using cp1252<\/a>[1]<\/sup>.<\/p>\n

\u00c8<\/code> encoded using cp1252 is C8<\/code> (hex).<\/p>\n

If you interpret C8<\/code> as an unsigned 8-bit integer, it’s 200.<\/p>\n

If you interpret C8<\/code> as a signed 8-bit integer, it’s -56.<\/p>\n

If you interpret C8<\/code> as a signed 8-bit integer, then extend it to a signed 32-bit integer, then cast it to an unsigned 32-bit integer, it’s 4294967240.<\/p>\n

So you have the expected value; you are simply interpreting it differently than you intended.<\/p>\n

  1. The encoding used to make systems calls (the encoding of LPCTSTR<\/code> and LPTSTR<\/code> arguments to system calls) in a build where UNICODE<\/code> isn’t defined is called the “ANSI” encoding. The actual encoding can vary from machine to machine. However, the “ANSI” encoding for (most? all?) English-language Windows machines is cp1252.<\/li>\n<\/ol>\n<\/div>\n
