From d672f8cb82878baf3834e938c4c416f4493952cf Mon Sep 17 00:00:00 2001 From: Ingo Schwarze Date: Sat, 15 Dec 2018 19:30:25 +0000 Subject: Several improvements to escape sequence handling. * Add the missing special character \_ (underscore). * Partial implementations of \a (leader character) and \E (uninterpreted escape character). * Parse and ignore \r (reverse line feed). * Add a WARNING message about undefined escape sequences. * Add an UNSUPP message about unsupported escape sequences. * Mark \! and \? (transparent throughput) and \O (suppress output) as unsupported. * Treat the various variants of zero-width spaces as one-byte escape sequences rather than as special characters, to avoid defining bogus forms with square brackets. * For special characters with one-byte names, do not define bogus forms with square brackets, except for \[-], which is valid. * In the form with square brackets, undefined special characters do not fall back to printing the name verbatim, not even for one-byte names. * Starting a special character name with a blank is an error. * Undefined escape sequences never abort formatting of the input string, not even in HTML output mode. * Document the newly handled escapes, and a few that were missing. * Regression tests for most of the above. --- regress/char/accent/nocombine.out_utf8 | 6 +++--- 1 file changed, 3 insertions(+), 3 deletions(-) (limited to 'regress/char/accent/nocombine.out_utf8') diff --git a/regress/char/accent/nocombine.out_utf8 b/regress/char/accent/nocombine.out_utf8 index 3aa441a2..497bf6fd 100644 --- a/regress/char/accent/nocombine.out_utf8 +++ b/regress/char/accent/nocombine.out_utf8 @@ -7,10 +7,10 @@ NNAAMMEE DDEESSCCRRIIPPTTIIOONN bare acute accent: e'e - escaped acute accent: e´e + escaped acute accent: e´ee acute accent sequence: e´e bare grave accent: e`e - escaped grave accent: e`e + escaped grave accent: e`ee acute grave sequence: e`e hungarian umlaut: e˝e circumflex: e^e @@ -25,4 +25,4 @@ DDEESSCCRRIIPPTTIIOONN -OpenBSD March 8, 2014 CHAR-ACCENT-NOCOMBINE(1) +OpenBSD December 15, 2018 CHAR-ACCENT-NOCOMBINE(1) -- cgit v1.2.3-56-ge451
