Function TestInvalidSurrogateLow

deep_spec_test.go:646–655

Verifies: SYS-REQ-062 [malformed] A high surrogate followed by an out-of-range second escape is a lone high surrogate → U+FFFD + the second escape reprocessed, matching encoding/json (DEFECT-260727-SNGT). SYS-REQ-062's error-return is superseded for this case.
