Text rendering with OpenGL in Croquet.

Hello,
Just want to draw attention to one tutorial, which focuses on advanced text rendering with OpenGL. (in D language)
http://dmedia.dprogramming.com/?n=Tutorials.TextRendering1
http://h3.team0xf.com/proj/fontTest8.zip - sourcecode (D language)
Could it be the right solution for unicode text rendering in Croquet using OpenGL too?
