Using System Language by Default
In vanilla Minecraft, the game uses the system language by default, but when using Fabric, this feature doesn't always work correctly.
This mod solves this problem: if the options.txt file doesn't exist or the game language hasn't been manually set by the user, Minecraft will automatically use your operating system's language instead of defaulting to English.
An important advantage of this modification is that it works correctly with KubeJS and is not affected by known compatibility issues.
