Introduction to uc-locale-ja_JP-15.0.0.1-17.cop.sha512

The ​​uc-locale-ja_JP-15.0.0.1-17.cop.sha512​​ is a critical localization component for Cisco Unified Communications Manager (CUCM) deployments requiring full Japanese language support. Designed under Cisco’s Global Localization Framework, this SHA512-signed COP file ensures compliance with Japan’s telecommunications regulations and enterprise standards, enabling proper rendering of Kanji/Kana characters, date/time formats (令和 era), and cultural conventions across collaboration interfaces.

Certified for CUCM version 15.0.0.1-17 and later, this locale pack resolves bidirectional text alignment issues in mixed Japanese-English environments while supporting Unicode UTF-8 encoding. Cisco officially released this package in Q1 2025 as part of its Asia-Pacific localization initiative, aligning with ISO/IEC 10646:2024 standards for CJK (Chinese-Japanese-Korean) character handling.
