Do either of those actually supply UTF-32 files along with data
files holding codepoint offsets?  UTF-8 is by far the most common
storage format for Unicode, and required by most network protocols.

Regardless, this has nothing to do with strings.  This involves
seeking to a byte position in a file, and extracting (and optionally
converting to the internal encoding) a chunk of text.
