test case
Test case attached. Expected result is "done". Actually results in:
Unhandled Exception: System.ArgumentException: Arg_InsufficientSpace
Parameter name: chars
at System.Text.UTF8Encoding.InternalGetChars (System.Byte* bytes, Int32
byteCount, System.Char* chars, Int32 charCount, System.UInt32& leftOverBits,
System.UInt32& leftOverCount, System.Object provider,
System.Text.DecoderFallbackBuffer& fallbackBuffer, System.Byte[]& bufferArg,
Boolean flush) [0x00000]

I also observed occasional segfaults until I validated strings myself.
