They are the same characters. Ergo this issue should be handled by the 
font. For example, in the font the character moves to its final 
position in Unicode (U+FE10), but the former (unofficial) position 
(U+E78D) contains a reference to U+FE10. This way, if someone has a 
document which uses U+E78D instead of the new codepoint, the user can 
still display the correct glyph. Means: keep it for backward 
compatibility, but provide a software tool to the user to convert his 
old documents so that the old PUA codepoints get replaced with the new 
official codepoints.
