Two points here.

First, the use of familiar squiggly lines is easier than unfamiliar 
ones.  And so there is advantage in using familiar ones as well as 
advantage in making common unfamiliar ones become familiar.

Second, knowing how to pronounce the squiggly lines helps, 
except maybe for those whose linguistic cognition is purely visual.

Except maybe for the extra effort in recognising when the same 
unfamiliar symbol is used.
