When Special Characters, like Chinese and Swedish, Present In Queue "Specific Data", On Clone or Change Queue Item Priority, The Queue Encoding Gets Changed In UiPath Orchestrator 2019.10 and 2020.4
This is a known issue in UiPath Orchestrator 2019.10 and 2020.4.
Enable the following flag in web.config - All new Special Characters will display correctly, but existing Special Characters will remain encoded:
<add key="OData.BackwardsCompatible.Enabled" value="true" />
For UiPath Orchestrator 2020.10 and 2020.10+, this flag is enabled by default.
