Comment(by cloos):

 Replying to [comment:12 sayamindu]:

 For reference, my reply on the upstream bug report:

 The new keysyms it defines overlay with existing syms.

 fe70 through fe7a are already in use.

 I like the concept — and advocated it in bug 11307 (cf comments 7 and on)
 —
 but we need to find a place for them.

 Since your patch defines 12 dead vowels we’ll need at least a block of 16.
 Are you aware of the needs for a similar input style for other such
 scripts?
 Is there any chance we’ll eventually need more than 16 dead vowels?

 In the 0xfe00 block it looks like the 0xfe40 and 0xfe80 through 0xfec0
 blocks
 are free.

 Using 0xfe40 would put the dead vowels right before the other dead keys.
 But
 using something like 0xfea0 would allow for more expansion.

 Can you take a look through UnicodeData and check whether any other dead
 vowels
 would be useful for the currently-encoded scripts?  A quick check suggests
 that
 the CANADIAN SYLLABICS, YI, VAI, LINEAR B, and CYPRIOT syllables as well
 as the
 CHEROKEE letters are relevant.

 ---

 Obviously not all of those UCS blocks are likely to be input on the OLPC,
 but a comprehensive survey of dead vowel needs is still preferred.  Will
 sixteen dead vowels slots be enough, or do we need thirty-two?
