Fix: Replace emojis with ASCII alternatives to fix GBK encoding issues (issue #2628)

[devin-ai-integration]

Description

This PR fixes issue #2628 by replacing emojis in the console formatter with ASCII alternatives to prevent blocking errors with GBK encoding on Windows systems.

Problem

Emojis in the codebase were causing blocking errors when using GBK character encoding (commonly used on Windows systems, especially for Chinese users). This made CrewAI unusable for some Windows users.

Solution

• Replaced all emojis in console_formatter.py with ASCII alternatives that are compatible with GBK encoding
• Added a test to verify that the console formatter works correctly with GBK encoding

Emoji Replacements

• ✅ -> [OK]
• ❌ -> [FAIL]
• 🤖 -> [AGENT]
• 🚀 -> [LAUNCH]
• 📋 -> [TASK]
• 🧠 -> [THINKING]
• 🔄 -> [RUNNING]
• 🔧 -> [TOOL]
• ✨ -> [NEW]
• 🌊 -> [FLOW]
• 🧪 -> [TEST]

Testing

Added a test that verifies the console formatter output can be encoded with GBK without errors.

Closes #2628
