Base64 yazdırılabilir karakterler içine bayt akışı dönüştürür. Yanlış bir şey yoktur.
'Little-endian' describes one of two ways a number can be converted into a sequence of bytes: little-endian = least significant byte first. Big-endian = most significant byte first. UTF-8 is a string encoding into a stream of bytes, and there is concept of endianness to be applied.
UTF16, however, encodes text into 16-bit words, and there are two ways to encode the words into bytes, and UTF16 comes in two flavors: UTF16LE (little endian) and UTF16BE (big endian). The same concept of endianness is also applied to UTF32, but this is not a common format.
If, by little-endian, you mean UTF16LE, then you have to decide to which format you want to re-encode the string (probably UTF-8).
You can use this function: mb_convert_encoding($input, 'UTF-8', 'UTF-16LE')
