It is not expected because nobody expected using LyX for hieroglyphs :)

However, I notice this there are in the 32bit plane. LyX uses internally 
such 32 bits characters, but Qt (our GUI library) only uses UTF16. We 
already had some bugs in the translation between the two.

It might also be that the bug is on Qt side.

Do you have an example file?
