You're just saying that "read" works as it should!

Check carefully the dictionary. What you may want is "read ... until". Otherwise, when you say "read ... using delimiter", you get a list of strings, the result of chopping the whole original file into pieces at the locations of the delimiter.

-----------------
set f to "" & (path to "temp") & "(make new name)"
open for access file f with write permission
write "hello" & (ASCII character of 254) & "world" to file f
close access file f
read f using delimiter (ASCII character of 254)
-- {"hello", "world"}
-----------------
