Definitely. It appears to be a bug in the set-string-nth primitive operation.
I'll fix it.
Just to be clear, >string does an element-wise conversion of a sequence of
integers into a string, so for example, "{ CHAR: a CHAR: b CHAR: c } >string"
(or equivalently "{ 65 66 67 } >string") gives the string "abc". If you're
expecting to get a string representation of an object, you need to use
"unparse" or "number>string". Some new users get confused by that.
