1. Introduction to uc-locale-zh_CN-12.5.0.1-4002.cop.sgn
This Cisco-signed localization package delivers native Simplified Chinese language support (locale identifier: zh_CN) for Cisco Unified Communications Manager (CUCM) 12.5(1)SU6 environments. Designed for enterprises operating in mainland China and Mandarin-speaking regions, it enables full localization of administrative interfaces, system prompts, and audit logs while complying with GB18030-2022 character encoding standards.
The 12.5.0.1-4002 version resolves display anomalies with full-width punctuation marks（，。；）and optimizes Pinyin sorting algorithms for directory services. Compatible with CUCM clusters running 12.5(1)SU3 or later firmware, it supports hybrid deployments across Cisco UCS C-Series servers and HyperFlex HX220c nodes.
