in repository libencode-perl.
commit 9bf4d66c0e524ca9dbffa266d204b5bf5efe74e3
Author: gregor herrmann <gre...@debian.org>
Date: Sun Dec 13 16:26:34 2015 +0100
Add patch dont-die-without-bom.patch.
The decode() routine died when no BOM was found. This patch, backported from
upstream's 2.77 release, changes the behaviour to fall back to BE
according to RFC2781 and the Unicode Standard version 8.0.
Closes: #799086

+ When you decode from UTF-(16|32) without -BE or LE without BOM,
