Well, for starters: isLetter() and isIdentifier() should give different results. U+02BC should be part of identifiers by default -- it is part of the alphabet of some languages. On the other hand, U+0027 is very often a syntax character, used as a 'quote' mark to indicate delimitation of an identifier or other symbol. --Ken
