Unicode in C++
summary
Covers concrete encoder behavior and migration choices: Unicode expands to 1,112,064 code points, UCS2 is obsolete, UTF‑32 fixes width but wastes space, UTF‑8 is variable‑width and dominant (claims 78% of top 10,000 websites and 65% of the top million), UTF‑16 uses surrogate pairs in the D800–DFFF range and needs BOM FEFF, UTF‑8 optional BOM appears as EFBBF, ICU supplies normalization, collation and regexes using ICU (UTF-16), Boost.Locale offers UTF conversions, collation levels and grapheme segmentation.
