Send non-breaking space (UTF8 00A0) through Json

[scand1sk]

Play Version

2.8.2

API

Scala

Operating System

Linux vion-precision 5.7.0-1-amd64 playframework/playframework#1 SMP Debian 5.7.6-1 (2020-06-24) x86_64 GNU/Linux

JDK

openjdk version "1.8.0_252"
OpenJDK Runtime Environment (build 1.8.0_252-8u252-b09-1-b09)
OpenJDK 64-Bit Server VM (build 25.252-b09, mixed mode)

Expected Behavior

The action Ok(Json.obj("foo" -> "foo\u00a0bar")) should give the HTTP answer containing the given Json with a non-breaking space.

Actual Behavior

I do not know whether this is a bug or a feature, but the non-breaking space is converted to a standard space.

Hi @scand1sk, is this a playframewwork issue or is it specific to play-json?

If the later, I can transfer ths issue to playframework/play-json.

[scand1sk]

Yep, it is probably specific to play-json.

Not sure to understand. For now cannot reproduce:

scala> Json.obj("foo" -> "foo\u00a0bar")
val res0: play.api.libs.json.JsObject = {"foo":"foo bar"}

scala> val origValue = "foo\u00a0bar"
val origValue: String = foo bar

scala> val obj = Json.obj("foo" -> origValue)
val obj: play.api.libs.json.JsObject = {"foo":"foo bar"}

scala> val decoded = (obj \ "foo").validate[String]
val decoded: play.api.libs.json.JsResult[String] = JsSuccess(foo bar,)

scala> val decodedString = decoded.get
val decodedString: String = foo bar

scala> decodedString == origValue
val res1: Boolean = true
