When attempting to include sprites in UI Toolkit labels using unicode escape sequences, the sprite fails to render, displaying only the unicode character text. While using the standard <sprite> tag within a UI Toolkit label correctly displays the assigned sprite, utilizing a unicode escape sequence, such as \U00F1F60A, where the sprite is assigned to 0xF1F60A in your sprite asset, does not render the sprite graphic. Instead, the raw unicode text is shown. This behavior indicates a potential issue with UI Toolkit's interpretation or rendering of unicode sprite references, particularly when contrasting it with the functional <sprite> tag.
