Specification
The requirement exactly as authored — its complete prose text and, where present, the formal FRETish sentence it compiles to.
When GetString is called on JSON containing Unicode edge cases such as BOM characters, zero-width joiners, or multi-byte sequences at string boundaries, the parser shall decode correctly or return a well-defined error without panicking.
the parser shall always satisfy !getstring_input_has_unicode_edge_cases | getstring_handles_unicode_edges_safely
Rationale & tags
Why this requirement exists, and how it is categorised.
Rationale & tags
Why this requirement exists, and how it is categorised.
Unicode edge cases (BOM, ZWJ, emoji sequences) are common in real-world JSON from international APIs and must not cause undefined behavior.
Verification & provenance
How this requirement was checked: the review trail, edit history, and the machine-analysis status terms (each ⓘ explains what it means).

Obligations
What this requirement must witness to be considered satisfied — the required evidence, and the tests that discharge each one.
No obligations recorded for this requirement
Proof obligations are recorded once evidence is generated. None have been captured here yet — this is expected, not a gap in the requirement itself. A required class of evidence the requirement must witness — the bridge between the requirement existing and it being proven.
Formula evidence
The formal formula behind this requirement, the variables it is written over, and the tests that exercise it (each term is explained inline).
