Obfuscated Text Improver

A Mod That Solves Minecraft's Obfuscated Text Issues

This mod fixes the game bug MC-277733 that causes serious performance problems when using obfuscated text. The issue occurs because the game selects characters for obfuscation from the entire available unicode range, creating excessive system load.
