LanguageProvider creates broken text

[DiscardedMarrow]

I've been playing around with the new data generators and thought it would be fun to create a swedish lang file (sv_se.json).

@Override
protected void addTranslations() {
	add(Items.PITEM_ITEM.get(), "Övningsföremål");
    add(Blocks.PBLOCK_BLOCK.get(), "Övningsblock");
}

It ended up looking like this:

{
  "block.justforpractice.pblock": "\u00C3\u2013vningsblock",
  "item.justforpractice.pitem": "\u00C3\u2013vningsf\u00C3\u00B6rem\u00C3\u00A5l"
}

While it should say:

{
  "block.justforpractice.pblock": "Övningsblock",
  "item.justforpractice.pitem": "Övningsföremål"
}

I don't know much about character encoding, but it doesnt seem like I'm the one doing anything wrong. I'm tempted to post a bug report but I'm strongly considering that I just need to set some encoding settings in IntelliJ. 
 

Thank you in advance.

The game is decoding the strings in the lang correctly, looks like whatever encoded them did it wrong.

Try \u00d6vninsblock and \u00d6vningsf\u00f6rem\u00e5l
