NoUnicode
A simple Minecraft plugin that blocks players from using Unicode characters, emojis, and special symbols in chat. Only allows standard keyboard characters (A-Z, 0-9, and basic symbols).

What it does:

• Blocks Unicode characters and emojis in chat messages
• Shows players which characters were blocked
• Allows server admins to customize which characters are allowed
• Bypass permission for staff members

How it works:

• Players without bypass permission can only use characters from allowed-characters.txt
• Blocked messages show helpful error messages
• Admins can reload settings with /nounicode reload

Perfect for:

• Preventing emoji/Unicode spam
• Keeping chat clean and readable
• Servers that want English-only chat
