patch 8.0.0519: character classes are not well tested commit https://github.com/vim/vim/commit/0c078fc7db2902d4ccba04506db082ddbef45a8c Author: Bram Moolenaar <Bram@vim.org> Date: Wed Mar 29 15:31:20 2017 +0200 patch 8.0.0519: character classes are not well tested 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.
