A byte-budget truncation returns a partial UTF-8 scalar · case 05

A byte-budget truncation returns a partial UTF-8 scalar.

Member previewVariant 5 · 3 implementations · 4 checks per implementation

Case contract

Given scalar text and a nonnegative byte budget, retain the longest UTF-8 prefix ending at a scalar boundary.

Why this case matters

A local executable model for consumers of structured text; oracle values are authored literals, not outputs copied from the repaired implementation.

One recorded failure

Sample boundary fixture

This sample comes from the broken implementation of a controlled reproducer.
