Internally, they're a series of bytes, but they are MEANINGLESS 
bytes unless you know how they are encoded internally.  Those 
bytes could be UTF-8, UTF-16, UTF-32, or any of a number of other 
possible encodings[1].  If you get the internal byte stream, 
there's no way to meaningfully operate on it unless you also know 
how it's encoded (or you're willing to sacrifice the ability to 
reliably get the string back).
