Inconsistent with nodejs

Hello, i’m using the following buffer

let b = Buffer.from([
191, 164, 235, 131, 30, 28, 164, 179, 101,
138, 94, 36, 115, 176, 83, 193, 9, 177, 85,
228, 189, 193, 127, 71, 165, 16, 211, 132,
228, 241, 57, 207, 254, 152, 122, 98, 100, 
71, 67, 100, 29, 218, 165, 101, 25, 17, 177,
173, 92, 173, 162, 186, 198, 1, 80, 94, 228, 
165, 124, 171, 78, 49, 145, 158
])

and toString(‘utf8’) results are different in NodeJS and in browsers.

It seems that some characters that some sequence which nodejs replace to U+FFFD are more lengthy than the replaced sequence in browser. so output utf8 string is different

the tests are already in node. to get them just do ./bin/download-node-tests.js

this and #164 should likely be merged
