We forgot to add to GdiPlusX a specific function to allow sending Unicodes directly, similar to the function DrawString.
But as you'll see below, it's really simple to adapt the original function and provide this possibility:
In the sample below you'll see the function "DrawStringW", that is just an adapted version from the original xfcGraphics.DrawString function.
It accepts the same parameters and overloads from the original function - the sole difference is the first parameter that was introduced - the Graphics object.
Another helper function - "HexToUnicode" was introduced. It converts a string containing Hex values separated by a space into the Unicode needed by GdiPlus.dll to draw the string.
Just run the script and you'll obtain a result similar to the one below:
Prerequisites
Visual FoxPro 9 and the GdiPlusX library from VFPX 
Please make sure that you have the latest version, because this sample may be using some functions that were added or fixed recently.
