From ff510d28f5ebd126869d718b1e3eb59ab8ef94b6 Mon Sep 17 00:00:00 2001 From: Yuri Pankov Date: Wed, 5 Dec 2018 17:10:06 +0000 Subject: [PATCH] MFC r339827: localedef: define characters in "space" class also as "print", except for the known conflicts ("control" characters can't be "print"able). POSIX doesn't explicitly forbid this, and actually includes character in "print".
