Environment

• OS: Windows 11
• Python: 3.12
• mempalace version: 3.3.0
• Console: PowerShell/CMD with GBK encoding

Problem

When running mempalace mine, the command fails with UnicodeEncodeError:

UnicodeEncodeError: 'gbk' codec can't encode character '\u2713' in position 2: illegal multibyte sequence

This happens in miner.py line 596:

print(f"  ✓ [{i:4}/{len(files)}] {filepath.name[:50]:50} +{drawers}")

The checkmark character ✓ (U+2713) cannot be encoded in GBK.

Workaround

Set environment variable before running:

chcp 65001 >nul 2>&1 && set PYTHONIOENCODING=utf-8 && mempalace mine <path>

Suggested Fix

Replace ✓ with ASCII character or make it conditional.
