Probably just standard compression techniques - the linked article is mostly discussing a standalone move, but there are a lot more options available when working with large strings of text (dictionaries, BWT, arithmetic coding, ...).<p>The downside is a lack of individual byte accessing without a lot of surrounding decompression work, but it&#x27;d be appropriate for stream processing<p>In fact the best compressed size is probably found by reducing some of the clever tricks in the article in order to expose more structure to a general compressor. Similar to running `precomp` or `antiX` before solid-packing multiple already-compressed files.
