This issue was solved here https://sourceforge.net/tracker/?func=detail&atid=301355&aid=1633552&group_id=1355 by adding a documentation chapter to clisp's next version: http://clisp.podval.org/impnotes/encoding.html#line-term-default See also: http://clisp.cons.org/impnotes/clhs-newline.html http://www.unicode.org/reports/tr13/tr13-9.html The original problem is best solved by a (setq *default-file-encoding* :unix) in ~/.clisprc.lisp -- Reini Urban http://phpwiki.org/ http://murbreak.at/ http://helsinki.at/ http://spacemovie.mur.at/ -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/
