Portability fixes in PPPredicateTest>>charactersDo: / parsedCharacterSet:
* It is my understanding that charactersDo: should iterate over all signle byte
characters. If so, the method suffer from off-by-one error, it should generate
characters with code points 0..255. 256 is actually a two-byte character.
Method changed accordingly.
* Use Character>>asString instead of `String>>with:` which is safer
w.r.t. multi-byte characters. Under Smalltalk/X, String may contain only
signle byte characters.
