Also I think (dont remember off the top of my head) that this note in
Lucene in Action refers to the fact that its base class
(BaseCharFilter) corrected offsets in O(n) at the time.

We fixed this to be O(log(N)) here as of 3.1:
https://issues.apache.org/jira/browse/LUCENE-2098

So I think its worth giving it a try before trying to code something yourself!
