Top 18 C++ Unicode Projects

Unicode

  1. {fmt}

    A modern formatting library

    Project mention: Stdio(3) change: FILE is now opaque (OpenBSD) | news.ycombinator.com | 2025-07-20

    With fwrite that would be another level of buffering in addition to FILE's buffer. If you are interested in what {fmt} is doing, a good starting point is https://github.com/fmtlib/fmt/blob/35dcc58263d6b55419a5932bd.... It is also possible to bypass stdio completely and get even faster output (https://vitaut.net/posts/2020/optimal-file-buffer-size/) and while it is great for files, it may introduce interleaving problems with things like stdout.

    > You can't even clearly define what an "atomic sequence of glyphs" is.

    Kinda. Grapheme cluster breaks are defined in Unicode, but they have all the baggage and edge-cases you'd expect from human languages evolving over time, so they can be encoded in as a few as a thousand rules : https://github.com/unicode-org/icu/tree/main/icu4c/source/da...
