Steps to reproduce

Create a .winget configuration file for DSCv2
In an IDE or text editor like VSCode, set the description for a resource to 😊😂🤣❤️ and save it
In WinGet studio, go to Manage a configuration file and load the configuration
Observe the emoji load correctly
Turn on edit mode
Click "Save configuration file"
Re-open the configuration file in the IDE
Observe the description has changed to \U0001F60A\U0001F602\U0001F923❤️

Expected behavior

Actual behavior

Environment

0.0.1

The issue names no source files or tests. Reproduce the DSCv2 configuration save flow with the emoji description, then trace the configuration-file save path from the WinGet Studio desktop app. Done means reopening the saved file preserves the original emoji characters instead of converting them to escape sequences.
