summary

Explains Unicode’s historical growth from 7-bit ASCII to ~145k code points with ~163 properties per character, and compares encodings UTF-8/16/32 noting that UTF-8 is byte-efficient and self-synchronizing. Covers normalization (NFC/NFD) to make text comparisons stable, grapheme clustering and locale collation, BOM and encoding declarations, emoji sequence size/costs (one example can be ~305 bytes), and practical runtime and interoperability impacts (around 50 KB needed for full support and common pitfalls).
