# IO.set_encoding_by_bom (from ruby core) --- ios.set_encoding_by_bom -> encoding or nil --- Checks if `ios` starts with a BOM, and then consumes it and sets the external encoding. Returns the result encoding if found, or nil. If `ios` is not binmode or its encoding has been set already, an exception will be raised. File.write("bom.txt", "\u{FEFF}abc") ios = File.open("bom.txt", "rb") ios.set_encoding_by_bom #=> #<Encoding:UTF-8> File.write("nobom.txt", "abc") ios = File.open("nobom.txt", "rb") ios.set_encoding_by_bom #=> nil
