Chafa 1.6.0: Wider

Here’s another one from the terminal graphics extravaganza dept: Chafa 1.6.0 brings fullwidth character support, so in addition to the usual block elements and ASCII art, you now get some mean CJK art too. Or grab as many fonts as you can and combine all of the Unicode into one big glorious mess. Chafa can efficiently distinguish between thousands of symbols, so it also runs fast enough for animations — up to a point. Since some users want this in environments where it’s not practical to build from source or even to have nice things like GLib, I’ve started adding statically linked builds. These are pretty bare-bones (fewer image loaders, no man page), so look to your steadfast distribution first. Speaking of distributions, a big thank you to the packagers. Special thanks go to Florian Viehweger for getting in touch re. adding it to OpenBSD ports, and Mo Zhou (Debian), Michael Vetter (openSUSE), Herby Gillot (MacPorts), @chenrui and Carlo Cabrera (Homebrew) for getting 1.6 out there before I could even finish this post.
