  "message": "Make StringViewTemplate constexpr-compatible\n\nRefactor `StringViewTemplate` to store `CharType` instead of\n`UnsignedType` in its underlying span. This allows constructors and\nmost methods to be `constexpr`, enabling compile-time string view\nmanipulation.\n\nKey changes:\n- Update `StringViewTemplate` member `span_` to store `const\n  CharType`.\n- Update constructors to be `constexpr` and use `UNSAFE_BUFFERS`\n  where necessary to satisfy static analysis.\n- Ensure empty views constructed from empty spans (e.g., cleared\n  vectors) resolve to `nullptr` data, preserving legacy behavior.\n- Define a local `constexpr ToLowerASCII` helper in\n  `string_view_template.h` to enable `constexpr` evaluation of\n  `EqualsASCIINoCase` without circular header dependencies.\n- Make various member functions `constexpr` (`begin()`, `end()`,\n  `operator[]`, `IsASCII()`, `EqualsASCII()`, `EqualsASCIINoCase()`,\n  `Substr()`, comparisons, etc.).\n- Add compile-time `static_assert` tests to `bytestring_unittest.cpp`\n  and `widestring_unittest.cpp` to verify `constexpr` behavior for\n  both `ByteStringView` and `WideStringView`.\n\nTAG\u003dagy\nCONV\u003d2983ff4c-f8b3-4c12-abb7-150795162e3c\n\nChange-Id: I7e8ee486a7a4977adeb9db25766a11d144e10db4\nReviewed-on: https://pdfium-review.googlesource.com/c/pdfium/+/150090\nReviewed-by: Lei Zhang \u003cthestig@chromium.org\u003e\nCommit-Queue: Tom Sepez \u003ctsepez@chromium.org\u003e\n",
