It's a BOM (byte order marker). Doesn't show up in vim
because vim is unicode-aware and will ignore it. See
http://www.unicode.org/faq/utf_bom.html#BOM

It was probably put there by the submitter's editor because his first name
(Mário) includes a non-ASCII character.

It's not so much of security risk, but it'll break any script (such as
sbopkg) that expects to parse PRGNAM out of the .info file. Try:

( set +x ; . JSONObject.info ; echo $PRGNAM )

It'd be worthwhile to add a check to the site's upload handler so it'll
reject text files (.SlackBuild, .info, slack-desc) that start with a BOM,
or maybe it could just remove the BOM.
