Introduction to ps-locale-ko_KR-12.5.1.8000-1.cop.sha512
This SHA512-signed Cisco COP file delivers full Korean language localization (ko_KR) for Unified Communications Manager (CUCM) 12.5.1 and IM & Presence Service deployments. Designed to meet South Korea’s KS X 1001 encoding standards, it ensures accurate rendering of Hangul characters in administrative interfaces, system logs, and call detail reports.
Released on March 25, 2025, as part of Cisco’s Q1 regional compliance updates, this package supports date/time formats, currency symbols (₩), and numbering conventions per Korean Industrial Standards (KS). It maintains backward compatibility with CUCM 12.x software trains.
Key Features and Improvements
-
Regulatory Compliance
- Implements KS X ISO 8601 calendar synchronization for holiday schedules
- Supports 16-bit Hangul Jamo character mapping (Unicode 15.0 Extended-B)
- Localized CLI prompts for Korean-speaking network operators
-
Security Enhancements
- Dual-layer SHA512 verification (file integrity + cryptographic signature)
- Blocks locale injection attacks via strict UTF-8 sanitization
-
Performance Optimizations
- 35% faster locale switching compared to 12.1.x Korean packages
- 500MB reduced memory footprint through optimized Hanja glyph caching
