From: Junio C Hamano Date: Mon, 16 Feb 2015 22:34:14 GMT Subject: [PATCH] send-email: ask confirmation if given encoding name is very short Message-ID: In-Reply-To: <20150206193349.GB4220@peff.net> Sometimes people respond "y" (or "yes") when asked this question: Which 8bit encoding should I declare [UTF-8]? We already have a mechanism to avoid accepting a mistyped e-mail address (we ask to confirm when the given address lacks "@" in it); reuse it to trigger the same confirmation when given a very short answer. As a typical charset name is probably at least 4 chars or longer (e.g. "UTF8" spelled without the dash, or "Big5"), this would prevent such a mistake.
