const char* DLGetMissingGlyphReportJSONA(int InstanceID);

Return values

Returns an object containing valid, the active policy, retained eventCount, and ordered events

Each event contains a monotonic sequence, document index, page, zero-based UTF-16 index, decimal code point, U+XXXX label, font name, font type, and operation name

Remarks

Supplementary-plane characters are reported once as one Unicode scalar rather than as two surrogate events

The report retains the latest 256 events in a ring buffer and does not clear them when read

Use ClearMissingGlyphReport after consuming the report
