Reading up on unicode

Unicode half‑star symbols exist since 2018 but have uneven font support; you can reliably display them by embedding a subset of Noto Sans Symbols 2 or using alternatives.

Charcuterie renders Unicode glyphs as vectors and compares them in embedding space to enable visual search and exploration of similar characters.

Punycode uses adaptive bias adjustment, delta compression, and variable-length base-36 encoding to efficiently encode Unicode into ASCII for DNS without shared state.
