experimental/desktop_photo_search doesn't handle utf8 correctly.

@mit-mit who should I chat to about built_value and decoding utf8 data correctly? I'm guessing I need to use characters with built_value somehow?

Could you give a bit more info on the issue you're seeing, please?

30,000' explanation is that I'm incorrectly rendering search requests that contain non-latin1 characters:

In digging into the problem (see https://github.com/flutter/samples/pull/587/files) I figured out a couple of things. First, our http package will default to decoding an application/json stream with the latin1 parser. Unfortunately for me, Unsplash API is returning API results using UTF8 without declaring it as such.

Thanks--indeed, looks like the issue is outside built_value.

And outside characters too. You'll have to set the encoding on the HTTP request manually.

import "package:http/http.dart";
...
  var response = await get(uri);
  var data = json.fuse(utf8).decode(response.bodyBytes);

(Do use the http package for HTTP requests, because using dart:io is not compatible with Flutter-for-Web).

With the above integrated in 8e0f5c4, it still trips up on the following on macOS (but renders fine in Chrome).
