Supporting the byte count for anything but 'encoding' is going to be terrible inefficient. It would require conversion between 'encoding' and 'fileencoding' on every command and/or storing the cached byte offset twice (and recomputing it when changing 'fileencoding'). Since utf-8 is more and more becoming the standard file encoding everywhere it's better to standardize on that. -- An indication you must be a manager: You can explain to somebody the difference between "re-engineering", "down-sizing", "right-sizing", and "firing people's asses". /// Bram Moolenaar -- [email protected] -- http://www.Moolenaar.net \\\ /// sponsor Vim, vote for features -- http://www.Vim.org/sponsor/ \\\ \\\ an exciting new programming language -- http://www.Zimbu.org /// \\\ help me help AIDS victims -- http://ICCF-Holland.org /// -- You received this message from the "vim_dev" maillist.
