Jarkko's view is that the combined hit of the size of the extra code to skip along the variable length encoding, the time taken to execute that code, (and I guess the cache misses it creates) is greater than the gain from saving space. Particularly when the regexp engine is written assuming O(1) random access. He thinks perl 5 would probably have been faster if it used UCS32 internally. Maybe ponie will. Nicholas Clark
