I want to write a simple function that converts UCS2 string into ISO8859-1:

ucs2 is a string of type "00480065006C006C006F" for "Hello". I'm
passing size because ucs2 isn't null terminated.

Is the UCS-2 really represented as a sequence of ASCII hex digits?

In actual UCS-2, each character is 2 bytes.  The representation for
"Hello" would be 10 bytes, either "\0H\0e\0l\0l\0o" or
"H\0e\0l\0l\0o\0", depending on endianness.  (UCS-2 is a subset of
UTF-16; the latter uses longer sequences to represent characters
outside the Basic Multilingual Plane.)
