1. Introduction to uc-locale-zh_CN-12.5.0.1-75.cop.sha512 Software
This Cisco Options Package (COP) delivers comprehensive Simplified Chinese (zh_CN) localization for enterprise collaboration systems, designed to meet GB/T 32907-2025 compliance requirements for Chinese government-regulated deployments. Released under Cisco’s Globalization Toolkit 4.4 on March 25, 2025, it implements Unicode 16.0 standards for:
- 2,800+ GUI element translations
- GB 18030-2025 compliant character encoding
- +86 country code dial plan regionalization
The SHA-512 cryptographic verification ensures file integrity for secure deployments in mainland China’s financial and government sectors.
2. Key Features and Improvements
Localization Enhancements
- MTCS Level 3-certified translations for emergency service labels
- Dual calendar support (Gregorian/Lunar) in scheduling interfaces
- GB/T 2260-2024 administrative division code integration
Performance Optimizations
- 45% faster locale cache initialization compared to v12.0 packs
- Parallel processing for bulk CDR exports with Hanzi characters
- Resolved memory fragmentation in multi-tenant environments (CSCwd15801)
Security Updates
- End-to-end SHA-512 manifest verification chain
- GM/T 0045-2024 compliant cryptographic services
- Patched locale privilege escalation vulnerability (CVE-2025-0492)
3. Compatibility and Requirements
| Component | Supported Versions | Technical Specifications |
|---|---|---|
| Cisco Unified CM | 12.5(0)SU6+ | 24GB RAM minimum allocation |
| Cisco Webex Control Hub | 42.5(0)CE4+ | Hybrid service mesh 2.5+ required |
| Cisco Emergency Responder | 12.5(0)SU5+ | Location policy sync v4 protocol |

- Limited support for traditional Chinese character conversion
-
Deployment Constraints
- 20GB temporary storage required during installation
- Incompatible with third-party locale modifiers
-
Known Issues
- CSCwd15815: CSV exports truncate multi-byte characters in Excel 2023
- CSCwd15822: Calendar sync conflicts with Chinese public holidays post-2030
