Ksh93 has "typeset -b" which defines vars for binary data (actually base64
encoded). E.g.:

[STEP 100] $ echo ${.sh.version}
Version AJM 93u+ 2012-08-01
[STEP 101] $ typeset -b var
[STEP 102] $ var=$( echo hello world | base64 )
[STEP 103] $ echo $var

[STEP 104] $ printf %B var
hello world
[STEP 105] $
