font + lang stuff issue

So i tried to make a resource pack that will replace the classic "Game Menu" text in in-game escape menu with an image but as soon as i hit F3 + T, i get a notification that minecraft failed to process the resource pack. I did the same with the output log enabled but i just got "error with reloading resource packs" as a warn. after a while i discovered that the issue is caused by "default.json" file located in assets/font folder. the file content is {     "providers": [         {             "type": "bitmap",             "file": "minecraft:font/title.png",             "height": 192,             "ascent": 48,             "chars": [                 "\uE000"             ]         }     ] } did i name it the wrong way or what?
