Yes this could be an interresting feature:
In the core we could make a difference bitween the 'real length ' of the 
display and the 'actually used length'. 
Moreover we would have to implement something like a table refering to 
cells that are 'down' or 'not working'..
For example wlets take a 20 length display content :
[abcdefghijklmnopqrst]

And lets suppose the 5th cell no longeer works, we would arrange the 
message like this :
[abcd efghijklmnopqrs]

Here the 5th cell is dead so we put a space (0x00 dot-pattern), and 
right-shift the end of our message content: so here, the actual 
display-length would be 19 cells.

Is that what you would like ?
