-// The StructurallyValid routines accept buffers of arbitrary bytes.
-// For CoerceToStructurallyValid(), the input buffer and output buffers may
-// point to exactly the same memory.
-//
-// In all other cases, the UTF-8 string must be structurally valid and
-// have all codepoints in the range  U+0000 to U+D7FF or U+E000 to U+10FFFF.
-// Debug builds take a fatal error for invalid UTF-8 input.
-// The input and output buffers may not overlap at all.
-//
-// The char32 routines are here only for convenience; they convert to UTF-8
-// internally and use the UTF-8 routines.
