Staring into space can occasionally be useful: I just remembered that I nearly forgot about this. I just replied (as you may have already noticed). Thanks for the info. I'm not quite sure how much investigation I'll need to do, but I can see alphabet-based token sizing being very useful for pure string compression, yeah. XZ seems to be a really flexible format but, unless I'm mistaken, it seems that implementations (such as the `xz` utility) seem to lean toward "one size fits all" instead of packing in+maintaining a "batteries included" basic (or maybe even extended) set of transformations/optimizations. It's kinda sad.
