If you want an array, then you can convert the string to UTF-32 or create an
array of PChar pointing to each character.
If you just want the n-th utf-8 character, then you can use UTF8CharStart.
If you need the n-th visible character (including BIDI and combined characters)
then you must use functions from the iconv lib or the winapi. Same for UTF-16
and UTF-32.
There is no encoding for random access to an unicode string.
