Backslash is not special there, so '[A\-Z]' matches 'A' and all characters in the range from '\' through 'Z'. The size of the range depends on the locale; in some locales the range is invalid (because '\' sorts after 'Z') but in some it's valid and may include 'd', which is what evidently happened for you. To get the behavior you want, use the pattern '[-AZ]' From debbugs-submit-bounces@debbugs.gnu.org Wed Sep 10 17:06:32 2014 Received: (at control) by debbugs.gnu.org; 10 Sep 2014 21:06:32 +0000 Received: from localhost ([127.0.0.1]:37050 helo=debbugs.gnu.org) by debbugs.gnu.org with esmtp (Exim 4.80) (envelope-from ) id 1XRp5z-0008Me-Bd for submit@debbugs.gnu.org; Wed, 10 Sep 2014 17:06:31 -0400 Received: from smtp.cs.ucla.edu ([131.179.128.62]:59653) by debbugs.gnu.org with esmtp (Exim 4.80) (envelope-from ) id 1XRp5x-0008MW-BX for control@debbugs.gnu.org; Wed, 10 Sep 2014 17:06:30 -0400 Received: from localhost (localhost.localdomain [127.0.0.1]) by smtp.cs.ucla.edu (Postfix) with ESMTP id 018A339E801B for ; Wed, 10 Sep 2014 14:06:29 -0700 (PDT) X-Virus-Scanned: amavisd-new at smtp.cs.ucla.edu Received: from smtp.cs.ucla.edu ([127.0.0.1]) by localhost (smtp.cs.ucla.edu [127.0.0.1]) (amavisd-new, port 10024) with ESMTP id aLi9gKyNemvn for ; Wed, 10 Sep 2014 14:06:20 -0700 (PDT) Received: from penguin.cs.ucla.edu (Penguin.CS.UCLA.EDU [131.179.64.200]) by smtp.cs.ucla.edu (Postfix) with ESMTPSA id 33331A60008 for ; Wed, 10 Sep 2014 14:06:20 -0700 (PDT) Message-ID: <5410BD4C.6050001@cs.ucla.edu> Date: Wed, 10 Sep 2014 14:06:20 -0700 From: Paul Eggert Organization: UCLA Computer Science Department User-Agent: Mozilla/5.0 (X11; Linux x86_64; rv:31.0) Gecko/20100101 Thunderbird/31.1.0 MIME-Version: 1.0 To: control@debbugs.gnu.org Subject: 18446 is not a bug Content-Type: text/plain; charset=utf-8; format=flowed Content-Transfer-Encoding: 7bit X-Spam-Score: -4.8 (----) X-Debbugs-Envelope-To: control X-BeenThere: debbugs-submit@debbugs.gnu.org X-Mailman-Version: 2.1.15 Precedence: list List-Id: List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Errors-To: debbugs-submit-bounces@debbugs.gnu.org Sender: "Debbugs-submit" X-Spam-Score: -4.8 (----) tags 18446 notabug close 18446 From unknown Fri Jun 20 05:37:14 2025 Received: (at fakecontrol) by fakecontrolmessage; To: internal_control@debbugs.gnu.org From: Debbugs Internal Request Subject: Internal Control Message-Id: bug archived.
