Thank you, I like insights like this, I have not used "source".
The simple solution I used was to recode using "while" as follows:

if version >= 700 "?vim6.2 printf "?tiny function
function Encode(str)
let out = ''
let i = 0
while i < strlen(a:str)
let c = a:str[i]
let n = char2nr(c)
let r = Urndm(0,8)
if r < 3 && c != '@' && c != '.'
let e = c
elseif r < 6
let e = printf("&#%d;",n)
else
let e = printf("&#x%x;",n)
endif
let out = out . e
let i += 1
endwhile
return out
endfun

function ReplaceWithEncoding()
let save = @@
normal! gvy
let @/ = @@
'<,'>s//\=Encode(@@)/
normal! `<
let @@ = save
endfun

vmap <F5> :call ReplaceWithEncoding()<cr>
endif
