We fixed many of these shortcomings in the OLPC Linux VM and image.  
Keyboard input works with dead keys, compose keys, and XIM. Clipboard  
works with unicode, formatted/rich text and images (this builds on the  
Sophie guys' work). There is rendering of various text scripts via  
Pango, including e.g. Devanagari with correct glyph shaping (Nepal is  
one of the pilot countries).
