Subject: [PATCH 6/6] utf8.c: avoid char overflow
Date: Mon,  9 Jul 2018 21:25:37 +0200	[thread overview]
Message-ID: <20180709192537.18564-7-dev+git@drbeat.li> (raw)
In-Reply-To: <20180708144342.11922-1-dev+git@drbeat.li>

In ISO C, char constants must be in the range -128..127. Change the BOM
constants to char literals to avoid overflow.
