U_DEBUG invokes the UI Toolkit window debugger. See Toolkit Debugger for information on using the debugger.

On Windows, U_DEBUG brings up the Toolkit window debugger in a separate window. The initial size and location of this window is user-definable using the DBG_X, DBG_Y, DBG_WIDTH, and DBG_HEIGHT environment variables. The font is user-definable using the FONT_DEBUG environment variable.
