“Unicode Strings: Why the Implementation Matters”
summary
CsString is a standalone, BSD-licensed Unicode string library that tags every string with its encoding, exposes code-point iterators, and converts between UTF-8 and UTF-16; it becomes QString8 when integrated into CopperSpice and fixes mangling in DoxyPress. The implementation emphasizes 32-bit code points, uses UTF-8 as the preferred storage, and proves itself with 1,200 automated tests plus ~85 human-readable tests; the team reports interoperability bugs fixed and practical size/performance gains.
