Version of example with before string without curly quotes. Works fine.
-----------------------------------------------------------------------

//	When a string contains smart quotes (single or double), then encodeString
//	does not work. The string is not written into the buffer and only 0 bytes
//	are in the buffer.


var buffer = Ti.createBuffer({ length: 46800 });

var before = 'This has no quotes';
var after;

var bytes = new Array(before.length);


Ti.API.info('before = ' + before);


Ti.Codec.encodeString({
	charset:		Ti.Codec.CHARSET_ISO_LATIN_1,
	source:			before,
	dest:			buffer,
	destPosition:	15600
	});


for (var b = 0; b < before.length; b ++) 
	bytes[b] = Ti.Codec.decodeNumber({
		source:			buffer,
		position:		15600 + b,
		type:			Ti.Codec.TYPE_BYTE
		});

after = Ti.Codec.decodeString({
	charset:		Ti.Codec.CHARSET_ISO_LATIN_1,
	source:			buffer,
	position:		15600,
	length:			before.length
	});


Ti.API.info('after  = ' + after);
Ti.API.info('buffer bytes = ' + bytes);




Console log without curly quotes:
---------------------------------
