  • I’m not sure if this is the right setting for technical discussion, but as a relative elder of computing I’d like to answer the question in the image earnestly. There’s a few factors squeezing the practicality out of this for almost all applications: processor architectures (like all of them these days) make operating on packed characters take more operations than 8 bit characters so there’s a speed tradeoff (especially considering cache and pipelining). Computers these days are built to handle extremely memory demanding video and 3d workloads and memory usage of text data is basically a blip in comparison. When it comes to actual storage and not in-memory representation, compression algorithms typically perform better than just packing each character into fewer bits. You’d need to be in a pretty specific niche for this technique to come in handy again, for better or for worse
