Hi Richard, It appears that you were spot-on with your guess about wonky things happening in character classes. Seemingly hex escape codes aren't allowed there. You'll have to either use a literal character, or if that isn't possible, do something ugly like this: /^[x#{"\xa3"}]?[A-Z]$/ # note the interpolation There might be another solution, hopefully so, but this should at least work if nothing else turns up.
