What changed

JSONParser toggled its in-string state for every quote, including escaped quotes. A valid string containing \" could therefore expose an embedded // as a comment and braces as JSON structure. Quote handling now accounts for preceding backslash parity when stripping comments, finding string boundaries, and matching brackets. Added a synthetic regression case with escaped quotes, a comment marker, and a closing brace inside the value.

Validation and scope

• git diff --check passed.
• The regression was added to the internal FlexTest suite but was not run locally: no C++ compiler/build tools (clang++, g++, cl, cmake, or ninja) are available. CI was not queried or awaited.
• No game/assets or submodules were checked out; no game or service was started. The sparse partial checkout contains only engine source/headers and root documentation.

Hi, thanks for the contribution! I think a recent refactor I did in 5fbd07 actually fixed this though, so I'll close for now. Let me know if there are remaining issues.

Thanks for the follow-up. I checked the current master parser: escaped characters are skipped while locating string boundaries, comment stripping preserves escaped characters inside strings, and bracket matching accounts for escapes. I do not see a remaining issue from the reported escaped-quote case, so the closure is fine.
