+// While std::filesystem::path can be directly constructed from std::string on
+// both Posix and Windows, that's not what we want on Windows. Per
+// https://en.cppreference.com/w/cpp/filesystem/path/path:
+
+// ... the method of conversion to the native character set depends on the
+// character type used by source.
+//
+// * If the source character type is char, the encoding of the source is
+// assumed to be the native narrow encoding (so no conversion takes place on
+// POSIX systems).
+// * If the source character type is char8_t, conversion from UTF-8 to native
+// filesystem encoding is used. (since C++20)
+// * If the source character type is wchar_t, the input is assumed to be the
+// native wide encoding (so no conversion takes places on Windows).
+
+// The trouble is that on Windows, from std::string ("source character type is
+// char"), the "native narrow encoding" isn't UTF-8, so file paths containing
+// non-ASCII characters get mangled.
+//
+// Once we're building with C++20, we could pass a UTF-8 std::string through a
+// vector<char8_t> to engage std::filesystem::path's own UTF-8 conversion. But
+// sigh, as of 2024-04-03 we're not yet there.
+//
+// Anyway, encapsulating the important UTF-8 conversions in our own subclass
+// allows us to migrate forward to C++20 conventions without changing
+// referencing code.
