You've already gotten good answers from others, but just in case
you're using CMUCL, the implementation-specific way there is to
add the :CLASS 'BINARY-TEXT-STREAM and :ELEMENT-TYPE :DEFAULT
optional args to the OPEN (or WITH-OPEN-FILE). That will let
you do both text (e.g., READ-CHAR) and binary (e.g. READ-BYTE)
operations on the resulting stream.

In particular, my CMUCL "-script" hack uses it to allow "#!"
scripts of both source files and FASLs, see:
