Char Set on Custom Properties

[J. Landman Gay]

Returning to this topic...we are in the process of creating new stacks 
in LC 7 while still running older LC 6 stacks with the same app. Stacks 
have custom properties containing text created on a Mac, and my app uses 
MacToISO() to display the text when running on Windows.

Some of the LC 6 stacks will be edited and saved in LC 7, others will 
remain as LC 6 for a while. My app needs to know whether the character 
set has already been converted so it can display text correctly. Is 
there a way to tell in a script?
