Introduction to ps-locale-cs_CZ-14.0.1.1001-1.cop.sha512

This localization package provides native Czech language support for Cisco Unified Communications Manager (CUCM) v14.0.1 deployments, specifically designed for compliance with Czech Republic telecommunications regulations (ČTÚ Directive 2024/013). It implements ISO 8601 date/time formats (DD.MM.YYYY HH:MM) and Czech diacritic rendering (č, ž, š, ě) across administrative interfaces, call detail records, and directory services.

Certified for CUCM clusters running 14.0.1 SU3+, the package integrates SHA-512 cryptographic verification aligned with FIPS 180-4 standards. Released in Q2 2025 per Cisco’s EMEA localization roadmap, it resolves text truncation issues reported in v12.5 deployments for Central European character sets.
