> var buf = new Buffer([ -108, 1, 72, 116, 104, 105, 115, 32, 105, 115, 32,
116, 104, 101, 32, 115, 116, 114, 105, 110, 103, 32, 70, 19, 0, 70, 18, 0,
-2, 37, 0, 114, 37, 0 ]);
Results in:
<Buffer 94 01 48 74 68 69 73 20 69 73 20 74 68 65 20 73 74 72 69 6e 67 20
46 13 00 46 12 00 fe 25 00 72 25 00>
> var str = buf.toString('binary');
'”\u0001Hthis is the string F\u0013\u0000F\u0012\u0000þ%\u0000r%\u0000'
If we want to see it's content, we can turn it back into a buffer with:
> new Buffer(str, 'binary');
<Buffer 94 01 48 74 68 69 73 20 69 73 20 74 68 65 20 73 74 72 69 6e 67 20
46 13 00 46 12 00 fe 25 00 72 25 00>
But I notice that if you leave the encoding off of the second one it'll
encode the whole thing as UTF8 and you get:
> new Buffer(str);
<Buffer c2 94 01 48 74 68 69 73 20 69 73 20 74 68 65 20 73 74 72 69 6e 67
20 46 13 00 46 12 00 c3 be 25 00 72 25 00>
Which matches your:
enc.toString('binary') [ -62 -108 1 72 116 104 105 115 32 105 115 32 116
104 101 32 115 116 114 105 110 103 32 70 19 0 70 18 0 -61 -66 37 0 114 37 0
]
So that's your problem, when you go to convert the "binary" string back
into a buffer, you're doing it with a utf8 encoding. You need to keep the
same encoding throughout.
