recode: set the useUnicode

[Richmond]

I am currently working on a series of automated routines to recode my 
Devawriter Pro stack
from Livecode 4.5 to Livecode 8/9 and . . .

my code is peppered with

set the useUnicode to true

and

set the useUnicode to false

statements.

Does anyone know if I have to remove them, or will they just sit there 
like one's appendix,
a useless 'something' from an earlier developmental stage?
