## 
## convert file from GB2312 to UTF-8
## 

path="$1"
unset opt
if [ "$2" = "force" ]; then
	opt="-c -s"
fi

	echo "nERROR: destination: $path does not exist.n"
fi

if [ -f "$path" ] ; then
	echo "Converting $path (gbk --> utf-8) ... "
	if file "$path"|grep -q UTF-8 >/dev/null ; then
		echo "Already converted"
	else
		iconv -f gbk $opt -t utf-8 "$path" > /tmp/$$.tmp
		if [ $? -eq 0 ] ; then
			echo "Success"
			mv -f /tmp/$$.tmp "$path"
		else
			echo "Failed"
		fi
	fi
