Introduction to uc-locale-zh_CN-14.0.0.1-64.cop.sha512
This SHA512-certified Cisco Options Package (COP) provides comprehensive Simplified Chinese language support for Cisco Unified Communications Manager (UCM) 14.0.0 deployments, addressing GB18030-2022 character encoding requirements for mainland China markets. Designed to resolve logogram rendering issues in voicemail transcripts and administrative interfaces, it enables full-stack localization for the zh_CN locale – including vertical text formatting in call analytics reports and Unicode Han unification compliance.
The “_sha512” suffix confirms FIPS 140-3 validated cryptographic integrity checks, critical for enterprise deployments under China’s Multi-Level Protection Scheme 2.0 (MLPS 2.0) cybersecurity standards. Cisco’s Q1 2025 collaboration release notes confirm this patch resolves 9 locale-specific vulnerabilities in UCM 14.x clusters, including improper GBK-to-UTF-8 conversion errors in Cisco Unity Connection 14.5 interfaces.
Certified for UCM 14.0(0)SU2 and later versions, the package requires 4.1GB storage per cluster node and integrates with Cisco Prime Collaboration 14.7 for centralized linguistic governance.
