Re: Text files in MCL 5.2

IIRC, MCL 5.2 reads in text files and converts to Unicode on the fly. 
And if you save the file then there is no going back to using that 
file in an earlier MCL release.

Not the solution you are looking for, but I am still using 5.1 for 
just that reason.

Is there some switch that allows the Unicode conversion to be turned off?
