If Cyrillic symbols are used, for example, "Задание", text becomes unreadable.
json file is in UTF-8.

But it's Villager Quests, not LevelZ :)

Ups XD sorry, I send one later

Mh I have actually no idea how to fix this

Try adding UTF-8 to build.gradle

processResources {
	inputs.property "version", project.version
	filteringCharset "UTF-8"

	filesMatching("fabric.mod.json") {
		expand "version": project.version
	}
}

tasks.withType(JavaCompile).configureEach {
	it.options.encoding = "UTF-8"
	
	it.options.release = 17
}

levelz-1.1.5.zip
Added it here, would appreciate a test

villagerquests-1.0.3.zip

Nope, the bug is there.

Honestly not sure how to fix this issue..

I call for help from other developers in here, cause this issue is important.

Maybe it was fixed now?
