Problem: Line in test commented out.
Solution: Uncomment the lines for character classes that were failing before
8.0.0519. (Dominique Pelle, closes#1599)
Problem: Character classes are not well tested. They can differ between
platforms.
Solution: Add tests. In the documentation make clear which classes depend
on what library function. Only use :cntrl: and :graph: for ASCII.
(Kazunobu Kuriyama, Dominique Pelle, closes#1560)
Update the documentation.
Problem: Sourcing a script where a character has 0x80 as a second byte does
not work. (Filipe L B Correia)
Solution: Turn 0x80 into K_SPECIAL KS_SPECIAL KE_FILLER. (Christian
Brabandt, closes#728) Add a test case.
Problem: Using the system default encoding makes tests unpredictable.
Solution: Always use utf-8 or latin1 in the new style tests. Remove setting
encoding and scriptencoding where it is not needed.
