I think the answer is never set the style of something that can have 
only one style to the style of something that can have multiple styles. 
In other words, the above command should be:

set the textstyle of btn 1 to the textstyle of char 20 of fld 1

Either the text run has a consistent style, in which case the result is 
identical to the earlier command, or the text run has a mixed style, in 
which case you are protected from that fact.

OR: you want to do something entirely different if the text run's style 
is mixed, in which case test for it.

I hope this helps. Feel free to contact me if you have any further 
questions.
