Hi,
the following session will probably explain the problem:
user=> (digit? \5)
true
user=> (ancestors java.lang.Integer)
#{java.io.Serializable java.lang.Comparable java.lang.Number java.lang.Object}
user=> (ancestors java.lang.Character)
#{java.io.Serializable java.lang.Comparable java.lang.Object}
The literal 5 is probably cast into an int/Integer, not a
char/Character. If you want to write char/Character literals, place an
antislash at the front of the literal.
Regards,
