The underlying conversion bugs referenced in #26 were already fixed in earlier commits (505373e, a440d09, 316f9f1), but no tests existed for UTF-16 ↔ UTF-32, UTF-16 → UTF-8, or UTF-32 → UTF-8 directions. Add six new test cases: - convert.16_to_8, convert.16_to_32, convert.32_to_8, convert.32_to_16 - convert.surrogate_pair_boundaries (U+10000, U+10FFFF, U+1F600 round-trips) - convert.utf16_invalid_surrogates (lone surrogates, surrogate-range codepoints) Closes #26 Signed-off-by: Christian Parpart <christian@parpart.family>
