Hi,

Thanks for investigating it.

No it's indeed a bug, could you please file a ticket.
By the way I've made a shorter version of your code:
-------
framework 'Cocoa'

s1 = NSMutableString.stringWithString("this is a test script.")
s1.sub!(/test/, "$B$"(B")
puts s1 #=> this is a $B!1(IAB(B script.

s2 = NSMutableString.stringWithString("this is a test script.")
s2[10..14] = "$B$"(B"
puts s2 #=> this is a $B!1(IAB(B script.
-------
(in fact sub! uses []= internally)

Cheers,
Vincent
