What is the difference between ascii UTF-8 and UTF-16?
The Difference Utf-8 and utf-16 both handle the same Unicode characters. They are both variable length encodings that require up to 32 bits per character. The difference is that Utf-8 encodes the common characters including English and numbers using 8-bits. Utf-16 uses at least 16-bits for every character.

When to use a BOM in UTF-16?
UTF-16. In UTF-16, a BOM ( U+FEFF) may be placed as the first character of a file or character stream to indicate the endianness (byte order) of all the 16-bit code units of the file or stream. If an attempt is made to read this stream with the wrong endianness, the bytes will be swapped, thus delivering the character U+FFFE,…
Do you need to know the byte order of a BOM?
For the 16- and 32-bit representations, a computer receiving text from arbitrary sources needs to know which byte order the integers are encoded in. The BOM is encoded in the same scheme as the rest of the document and becomes a non-character Unicode code point if its bytes are swapped.
What does the you + FEFF byte order mark mean?
The byte order mark (BOM) is a Unicode character, U+FEFF BYTE ORDER MARK (BOM), whose appearance as a magic number at the start of a text stream can signal several things to a program reading the text: The byte order, or endianness, of the text stream;
What does FF FE mean in UTF-8?
From this wikipedia article, FF FE means UTF16LE. So you should tell iconv to convert from UTF16LE to UTF8: Also answered on StackOverflow: How can I remove the BOM from a UTF-8 file? @rici has a good answer.
