No, they're numeric.  "integer" here is a type, not the mathematical 
thing.  This works:

intToUtf8(as.integer(c(66,55)))

The docs don't mention this requirement, and it does seem somewhat 
unnecessary; I'll look into it.

You're lucky I didn't read to the end of your message:  that's a pretty 
old version.  Please test on current versions before reporting problems.
