if isBinary check fail, it'll be encoded as utf8 and got wrong response body

function manipulateContent(request, entry, replacements) {
    var entryResponse = entry.response;
    var content;
    if (isBinary(entryResponse)) {
        content = entryResponse.content.buffer;
    } else {
        content = entryResponse.content.buffer.toString("utf8");
...

// FIXME
function isBinary(entryResponse) {
    return /^image\/|application\/octet-stream/.test(entryResponse.content.mimeType);
}
