We escape only characters below 32, plus " and \. UTF-8 should be apssed through verbatim. Since char can be signed (and usually is), the check broke and happened to escape UTF-8 encoded bytes too. This broke UTF-8 completely. Note that we don't check for broken or invalid UTF-8, such as described both in the client API and IPC docs. Fixes #1874.
