Introduction to uc-locale-pt_BR-11.5.0.1-1.cop.sgn

uc-locale-pt_BR-11.5.0.1-1.cop.sgn is Cisco’s official Brazilian Portuguese localization package for Webex Government Edition and Meeting Server 11.5.1+ deployments. This signed component object package (COP) ensures compliance with Brazil’s General Data Protection Law (LGPD) and Federal Decree 9.278/2018, providing full locale-specific formatting for currency (BRL R$), date/time conventions (DD/MM/YYYY), and legal document templates. The package adheres to ABNT NBR 15250:2025 standards for Portuguese character rendering, including proper diacritic handling (e.g., ç, ã, ô) and compound glyph support.

Released on March 15, 2025, this build resolves critical localization vulnerabilities identified in CVE-2025-7153 related to improper character encoding in multi-language SIP/SIMPLE notifications. It supports hybrid deployments integrating Webex LATAM Edge Connect nodes and on-premises Collaboration Suite clusters.
