In mlterm, we have assumed that a combined char can be represented
by up to seven UCS4 codes.

Since reserving (W*7) chars instead of (W*H) for a line 
is considered to be too wasteful,
extra memory for combined chars are dynamically allocated
only when necessary.

We could use linked-list to support arbitrary long sequence.
But I don't think we can bear to store a pointer to next node 
(=extra 4 or 8 bytes) for every character.
