I have a file which may be in ASCII or UTF-8 format. I can know which format it is through Notepad++. But can some one tel me a tool that could show me in which format the file is through command prompt.
Example: Open Command Prompt,
C:><Some Command> FileName
which should give me the file format like ASCII or UTF-8.
This is a duplicate of this question here which has a great answer (not by me I might add)
EDIT
I am pretty sure there is not way that is reliable to do this, usually you are told the encoding of a file, sure you can look for a Byte Order Mark (BOM) at the start of the file but its not mandatory and so is not a true indicator unless you know for SURE its supposed to be there.
Unless someone knows differently I don't think its possible to work out from scratch you have to have some clue about the encoding used.
