Robert Muir commented on LUCENE-1799:
-------------------------------------
btw that patch is huge because i just sucked in the icu charset stuff to have
an implementation that works for testing...
its not intended to ever be that way as we would just implement the stuff we
need without this code, but it makes it easier to test since you dont need any
external jars or muck with the build system at all.

> In lucene-1793, there is the off-topic suggestion to provide compression of
> Unicode data. The motivation was a custom encoding in a Russian analyzer. The
> original supposition was that it provided a more compact index.
> This led to the comment that a different or compressed encoding would be a
> generally useful feature.
> BOCU-1 was suggested as a possibility. This is a patented algorithm by IBM
> with an implementation in ICU. If Lucene provide it's own implementation a
> freely avIlable, royalty-free license would need to be obtained.
> SCSU is another Unicode compression algorithm that could be used.
> An advantage of these methods is that they work on the whole of Unicode. If
> that is not needed an encoding such as iso8859-1 (or whatever covers the
> input) could be used.
