Windows does not use Notepad to edit text files

Excerpt from: Xuefeng Liao

Never edit any text file with a Notepad that comes with Windows. The reason is that Microsoft Development Notepad team used a very mentally retarded behavior to save UTF-8 encoded files, they are smart to add 0XEFBBBF (hex) characters at the beginning of each file, you will encounter a lot of incredible problems, for example, the first line of the page may show a "?", obviously the correct procedure to compile a report on grammatical errors, and so on, are caused by the mentally retarded behavior of Notepad. Suggest you download notepad++ instead of Notepad, not only powerful, but also free! Remember to set the notepad++ default encoding to UTF-8 without BOM
