Title: bi: Fix crash for services with special characters Class: fix Compatible: compat Component: bi Date: 1716389565 Edition: cre Level: 1 Version: 2.2.0p27 Previously, the BI would crash if a service name had special characters (e.g. emoticons). The error was: "Internal error: ('utf-8', 'bi:aggregation_lookup..., 'surrogates not allowed')". The BI now handles and shows special characters correctly.
