Introduction to uc-locale-sv_SE-12.5.0.1-75.cop.sha512

This localization package provides ISO 639/3166-compliant Swedish (sv_SE) language support for Cisco Unified Communications Manager (CUCM) 12.5.0.1 deployments. Designed for Nordic region compliance, it implements Swedish-specific linguistic rules including date formatting (YYYY-MM-DD), numeric separators (space as thousand delimiter), and extended character support for collaboration endpoints like Å/Ä/Ö letters.

Released under Cisco’s Q3 2025 software maintenance cycle, the package incorporates SHA-512 cryptographic validation to ensure file integrity during deployment. Compatible with CUCM 12.5.0.1 SU6 and later versions, it resolves localization inconsistencies reported in previous iterations for Swedish-speaking markets.
