1) In pango we have faced problem of backspace due to decomposition.
i.e. U+0958  was getting decomposed into U+0915 and U+093C, so for 
entered character was required 2 backspaces to delete.

2) CCMP feature of OT fonts also provide this options to font developer. 
(i have used this lot in Arabic fonts since U+0600 charts contains )
